“An extraordinary debate is going on right now inside and outside AI companies about whether the possibility of AI destroying humanity is more or less than 10%. The European Union is moving ahead with a comprehensive AI regulatory framework, but the UK continues to rely on existing regulation.”
“The Pope also highlighted how the billions of online digital twins constitute an unprecedented concentration of power in the hands of a small number of men. Among the many consequences of the 40 years of neoliberalism repeatedly called out by the Prime Minister is a libertarian attitude to technology.”
“But this stealth digital twinning violates the integrity, uniqueness and very personhood of our constituents and of all of us. Digital twins can take many forms, from content creation algorithms and deepfakes to chatbots that reflect aspects of our personalities back at us. It is particularly worrying when children are the target.”
“The automated version of our kids will grow with them, using the power of AI to target advertising and products at them, and worse. The Science, Innovation and Technology Committee has heard about some of the tragic consequences of online grooming by algorithms and chatbots—a vulnerable boy persuaded to kill himself; a vulnerable girl fed…”
“In the arts, entertainment and tech industries, many performers are agreeing to the creation and use of digital replicas as part of their work—think of ABBA Voyage. But performers increasingly encounter unauthorised digital replicas of themselves, which pose a threat to their career, livelihood and reputation.”
“Since then, deepfakes have proliferated. The hon. Member for Mid Norfolk (George Freeman) was shown crossing the Floor in Parliament to join Reform, to his constituents’ consternation and his own—it was a fake. Then there were the horrendous photos of naked women and girls that Elon Musk’s AI created on demand.”

“The introduction through the Bill of TSRs will take that even further, so we would be very confident that we have got a good enough structure there to ensure that any concerns that any part of Government had would be captured and dealt with, and Ofcom is also now in a position to regulate. The question about relying on just the one supplier is less a concern about security and more one about the commercial resilience of that position. Howard can probably say a little bit more about the standards and the technical questions around that.”
“Thirdly, on behalf of Catherine West, on international collaboration, what presence do you have on standards bodies? Can you say what your budget is for research and development so that we can see how that compares with the £250 million on offer? Alex Towers: I will defer to Howard on the questions about standards and technical details. On your point about the relationship with Government, I do not think that any of us were around in 2005, but I know that there is some sort of contested story about exactly who was told what about the introduction of Huawei. You would— [ Inaudible . ] We have moved a long way on that. We have a very close working relationship with the NCSC and with other parts of Government, and we would be very confident that we are constantly in contact with them about exactly the mix of suppliers that we are using.”
“Q Thanks very much for joining us. We have heard that open RAN will not be mature for another eight years. Do you agree with that assessment? In that case, as you have outlined, we have two vendors and potential financial concerns about one. Can you say categorically whether it is possible to have network security with only one full-scale vendor to choose from and whether it is possible to have that with two? Secondly, we heard from Sir Richard Dearlove, the previous head of MI5, that when Huawei was first used as a vendor or equipment supplier by BT, it was not considered worth informing Ministers of that fact, despite what he considered to be evident security concerns. Can you say what in the Bill changes that so that the Government of the day will be better aware of ongoing and future security concerns?”
“On your final question about research, we are in the top five investors in R&D in the UK—we invest in excess of £500 million a year across both research and development. In fact, the only companies that research more than us in the UK are the pharmaceuticals. I have 280 researchers based in the BT labs at Adastral Park near Ipswich and they, plus a standards organisation —we also draw in from engineers across my organisation—remain really actively involved in the standards bodies. I welcome what colleagues from the other operators say and think it is really important that we maintain that as a UK presence and as a European presence to ensure that we are not lost in the middle of any risk of divergence between the US and eastern and Asian countries and China. I would implore us all to work hard to ensure that that does not happen.”
“Howard Watson: On the vendor point, to summarise the approach that we are taking, we stopped purchase at the end of December, we will stop deployment in September of this year, we get down to 35% by two years hence from the end of next week, and then we have it removed from the mobile network by December 2027. I think that timeframe works well for us with introducing effectively a third supplier into our mobile network in terms of that 2027 point. It certainly helps mitigate any future steps in terms of a two-to-one. I would not bank on it taking a full eight years to have an open RAN opportunity. As we heard from Andrea, colleagues at Vodafone have already started deployment . The real challenge there is about being able to use open RAN in dense urban areas where the technology works at its hardest, shall we say.”
“Q Do you not think resilience is part of security? Is a network secure if it is not resilient? Alex Towers: I think they overlap and that is one of our questions about the drafting of the Bill. There is clearly a relationship between those two things, and the concern about the timeframes for the removal of Huawei, for example, has been partly about ensuring that we have operational resilience during what is going to be a very complicated engineering programme to take out all its kit without losing resilience, in the sense of outages and blackouts for customers. Some of the Bill’s provisions talk about outages, but there is a difference between outages for operational maintenance and updating of kit and outages because of a security issue or attack. It is going to be quite important to pull those threads apart a little bit.”
“We at BT have now built for 3.5 million homes. We have a plan, which we have talked about—this is with the right conditions—to get to 20 million. We do need that 35% to be part of that plan because, again, introducing alternative vendors is challenging.”
“Please remember that it is only in the access part of the network, so the fibre—the device in the exchange that connects to that. In the core of the fixed network, we have no presence of high-risk vendors. So we do believe that is manageable. We worked really closely with DCMS and NCSC to arrive at the 35% threshold that was published a year ago, and we think maintaining that in the fixed network is proportionate and sufficient to ensure security there, combined with the oversight that, again, we continue to support from the HCSEC and NCSC to ensure that we are inspecting everything that goes into the network. I will also say that it is essential that we do take that approach because, as you know, we have large ambitions to increase full-fibre coverage in the UK. Ofcom reported in December that that was now at 18%.”
“Q I was interested in what you said about the weakest link for networks. I agree wholeheartedly with that. What are your thoughts on fixed networks? While the Government are consulting on fixed networks, apparently they are not minded to require the removal of high-risk vendors from existing fixed networks. You have Huawei in your fibre-to-the-cabinet network. Do you agree with that? Do you think that there is a reduced risk in the existing fixed network? Do you intend to remove high-risk vendors—that is, Huawei—from existing full-fibre build? Do you think that presents a security risk? Howard Watson: We do believe that fixed networks, whether full-fibre or fibre-to-the-cabinet, have a different risk profile—a lower risk profile—from mobile networks.”
“Q Can you say why the risk profile is different for fixed as opposed to mobile? Howard Watson: Fundamentally, you are dealing with a customer that is a fixed end point, so you are not having to provide handover between different sites as you do in mobile. Essentially, we are taking an electrical signal, modulating it into optical and converting it back to electrical at the other end, in very standard ethernet-based protocols. It is therefore really easy to see if there is a problem, so if something was infiltrating the network, we would spot it very quickly. Also, it is a very segmented network. The FTTC network has a granularity of over 85,000 cabinets in the UK, and the FTTP network has splitters for every 32 homes. Any issues are very easy to spot and so it is much easier to keep secure.”
“Q Finally, with regard to having only two vendors for the mobile network for a number of years, can I ask two questions? I think that there has been a little discussion about resilience versus security, but if you are dependent on two vendors, one goes down and you are dependent on the other, would you say that that network was still secure? And is an increase in prices for equipment likely to accompany the reduction in the number of vendors available?”
“Obviously, the conversation about high-risk vendors is prevalent in other areas, but I would say that in terms of bringing in a regime that covers the entire telecoms sector, this seems to be a world-leading initiative. Hamish MacLeod: Chi, I am certainly aware of what other countries are doing as regards high-risk vendors. The operators absolutely accept the Government’s policy and the 2027 timeline. The important thing now is to stick to that timeline, because it allows not only for an orderly removal of the HRV equipment, but for alternatives to develop and emerge as viable competitors to the remaining companies.”
“Q Thank you, Mr McCabe. I was going to ask on behalf of my colleague, Catherine West, who cannot be here because we have chosen to sit physically rather than remotely. [ Interruption. ] It has been decided that we will sit physically. Her question is about international comparisons. Are you aware of what is happening with other countries’ security frameworks in addressing Huawei and high-risk vendors? Are you aware of any international comparisons? Matthew Evans: From techUK’s point of view, obviously our members—you heard from some of them this morning, and you have more this afternoon—operate across a number of different territories. We seem to be the furthest, or the most advanced, in bringing into place quite a holistic security regime. That is in the first half of the Bill.”
“Q So, what are other countries doing that you are aware of? Hamish MacLeod: The States, New Zealand and Australia have all excluded Huawei, among others. We could supply you with a full list if that is needed.”
“Finally, the Bill gives the Secretary the State a huge amount of powers to set out requirements to remove vendors and for Ofcom to inspect what operators are doing. Do you think that might have an impact on international foreign investment in the UK telecoms sector, and are you confident that the right sort of technical, security and democratic scrutiny is in place? That is three things: hardware, research and development, and scrutiny.”
“I am also really interested in what you said, Mr Evans, with regard to research and development. I absolutely agree with you that we clearly need investment in research and development if we are to lead in hardware and in open RAN and software. You said that the £250 million was focused on R&D, but it is actually focused on testing. It does not really do much for research at all, as far as I can see. You also referred to the diversification strategy as a strategy and not a plan, so do we need investment in research and development? Is the £250 million, which I think—I am looking at the Minister now—is over five years, a significant amount of investment in research and development for the mobile sector and tech sector generally?”
“Q Thank you, Mr McCabe, and I thank our witnesses for joining us. I started out in telecoms in 1987, as a hardware engineer. Since then, as you have indicated, our hardware sector in telecoms has disappeared. Hamish, you have talked about the equivalence with the computer sector, which has experienced a similar demise over the past 40 years. I am interested in whether it is possible to have a secure telecoms supply chain without having secure hardware. What are your views on that? The draft vendor designation talks a lot about the geopolitical influence of China rather than about the technical requirements, and that would be as true for hardware as it is for software. Do you think it is possible to have secure supply chains without having sovereign or friendly hardware capability?”
“This needs to work with the grain of industry, so it is important that industry is able to participate in this funding. I think it sent a strong signal.”
“Q To clarify that point, you are happy with the existing level of scrutiny and involvement of the security services in the development of the framework and the review of the telecoms supply chain, and so on, and you would like to see that continued. When it comes to investment, could you say a little bit about the £250 million over five years, which is, say, £50 million a year? Is that a significant amount of research and development investment in the tech sector in this country? Matthew Evans: I think it sends quite a strong signal to the market of the Government’s intent. If we published the strategy without the funding, it would not have sent the same signal. We have seen NEC, for instance, commit to opening an open RAN test centre in the UK. I think that is a signal of how the market is starting to react.”
“With R&D, there is pure R&D—what you do in labs—but there is also the testbed activity, which is a very important aspect, and trials at scale and all those things. Working with the operators, bringing in international partners and leveraging what is going on elsewhere in the world will all be important. Matthew Evans: The important word there is “leveraging”. Telecom spend on R&D, both traditional and in open RAN, runs into billions and billions of pounds each year, but we can use that £250 million to leverage greater investment. It has to be with the grain of what the industry is delivering, so we can attract more of that investment. If we can be world leaders in the adoption of open RAN, that is key, and we will attract that investment. That is why I think the supply has to match up with the demand side fully.”
“Q I did not think I would get a chance to ask further questions. I respect your reluctance, if you like, to voice criticisms at this stage, but can I just get a further idea on the level of R&D spend in the sector? We heard from British Telecom this morning that it spends £500 million a year. I imagine it is not the only company to spend. Do you have a view of the level of R&D spend? You talk about the £250 million being a signal. Am I right in thinking that a lot more investment needs to be attracted into the UK telecoms sector in order to really move the dial? That is what we are talking about, is it not—really moving the dial on UK telecoms capability? Hamish MacLeod: Absolutely. The £250 million was very much described as an initial £250 million, because you are right that moving the dial will take significant investment.”
“Catherine is always interested to understand what international comparisons there are, but I think that that has already been addressed, so thank you; she will be grateful to you.”
“Dish, for example, is doing only 5G, but we obviously look at requirements all over the world and we appreciate that, in certain parts of the world, there is still a lot of 2G and 3G presence, and, of course, 4G will be there for a long time. We have a solution that can handle 2G, 3G, 4G, 5G, and if you are talking about a 12-month window, we can definitely provide a complete greenfield solution for those four technologies. Regarding the hardware aspect, everything other than the real radio that goes on the tower and does the transmitting and receiving is largely general computing open silicon—”
“Q Thank you for joining us today. Having read your bios, I am impressed by the breadth, geographic as well as technical and operational, of your experience. To make this concrete for me and others, let us say we had a new mobile network operator in the UK tomorrow. Could you—I will ask someone to answer on behalf of Mavenir and someone on behalf of NEC—provide a 2G, 3G, 4G, 5G network tomorrow, or in 12 months? As a software network, what physical boxes or hardware would it be running on? As part of that, what UK or other providers would be in your supply chain? Pardeep Kohli: Maybe I can take that. To answer your question, if there is a greenfield operator in the UK that is similar to Dish, which we are working with in the US, we can definitely provide that.”
“Sorry—say that again. I could not hear that. What is the rest of it? Pardeep Kohli: It is general-purpose open compute; it is already available hardware.”
“It is computing—it is processors. Pardeep Kohli: That is correct. You get processors for CPU or general-purpose computing, or even if there are some accelerators, which we use for some specific algorithms, even though they are openly available from companies like Xilinx and Nvidia. They make those chips and we can use them to do some of the functions; but they are openly available, and you can buy that today. That is what carriers are doing. They are building the new networks. Regarding the hardware that goes on the tower, that depends on the frequency band you allocate, so if there is an operator coming in that is on a frequency band that the existing operators do not have, whoever the vendor is would have to build those radios anyway, and it takes about nine to 12 months to build those.”
“We are actually building some radios ourselves for the frequency bands that are not available from our partners, so if NEC has a radio we use the NEC radio, but if it does not have a radio and Fujitsu does not have a radio and if you want to get into that market, we start building some of those radios ourselves. So we actually have, now, opened a centre in the UK, to build some of those radios, and we are working with Facebook and together we are building some of the radios for a frequency band not currently open.”
“Q Who builds the radios? Pardeep Kohli: Today, because it has always been proprietary solutions, that is where the challenge comes for companies like us, because it is demand and supply. Until open RAN came in, you really could not build this channel on radio, because there was no demand for it. So today the radios get built only by companies like Huawei, Ericsson, Nokia—I know NEC is building a few of them; but now, with open RAN, there are new players coming up. NEC, for example, is building radios outside of the Japan market. Fujitsu has now started building radios.”
“Q So you couldn’t provide a network tomorrow, but you could provide a network in how long—a 2, 3, 4 or 5G network? Pardeep Kohli: So if the frequency band radios are available today, which are right, then we can actually build it in 12 months—the complete network; but if the bands are not available and we have to build those radios then, maybe, by the end of next year.”
“Q And NEC? Chris Jackson: Just to add to what Pardeep has been saying, I think open RAN is not about, necessarily, any one company providing an all-encompassing solution. So at the moment, for NEC, we would provide 4G and 5G radios, but in terms of 2G and 3G we will work with our partners to provide that solution, so we would leverage third parties in order to provide that all-encompassing solution. I think that is the way that open RAN will work moving forward. As I say, you will not see any one company dominating one particular area. It is about bringing best of breed together. In terms of the actual hardware platform, in terms of 4G and 5G, NEC will provide that radio, but as I mentioned for 2G and 3G we would look to other vendors to provide.”
“Q And who are those other vendors? Are they UK, Europe or US-based? Chris Jackson: The majority would be US-based now, but again, we are not restricted to that. As a systems integrator, which is what you will basically need, moving forward, we would work with whichever vendors were the best of breed for that particular scenario.”
“Q You seem to be saying, then, that you are in a position to compete with Nokia and Ericsson as of today. Is that what you are saying? Chris Jackson: We would not compete with Nokia and Ericsson in terms of standard RAN, but the whole idea is that we would look to bring open RAN technology. That is the direction that NEC is supporting. If you ask me whether we could step in today and provide that capability, we believe yes, we could.”
“These things are more important, and they are the reason why, although operators are in the middle of that transformation, it is taking a bit of time.”
“For example, most of the 5G deployed today just uses additional frequencies on the existing sites that they have deployed with 4G, 3G and 2G. This is not what I consider full 5G, with all the characteristics of low latencies and so on. You need to start to think about the densification of sites. The Government can help a lot—with policies, by helping to define new capabilities, and by allowing the operators to change their architecture by enabling them to get more sites, and get permits more easily to build new sites. These sites will not be like sites today; on these sites, there will be lot of carriers, a lot of technologies, and a lot of frequencies. As Pardeep said, a site today is probably just a radio unit that connects, through an internet connection—not necessarily just fibre—to a software data centre.”
“It is not hardware and software together; it is software and hardware disaggregated, and that of course requires some different capabilities. It is the same as when we passed from circuit voice to packet voice. Some people here may not get the example completely, but it is just a different point of view. That does not mean that it is more complex or whatever; it is just a different point of view, and you need to change. We know that change is not an easy thing. That is the first aspect that we need to take into consideration. The second aspect is that, despite the technology that is available, you still need to consider the in-life service that you need to swap over. You have to consider that you did some planning or design based on certain principles that were available before, and you need to rethink how you are going to do that.”
“We supply voice services, messaging services and everything else. You mentioned the initial deployment of open RAN by Vodafone this morning. That relates to us, because we are the supplier that it has deployed and is continuing to deploy. We are actually deploying sites for it. I think that you have to look at two aspects when you are on an operator’s side. I am speaking from experience. It is not just about the technology; it is also about your processes and how you are able to move forward and change your mindset. I think that operators have a lot of complexity. We sympathise with them, of course—it is not an easy environment—but there are a couple of mindsets that they need to over-pass, if you let me use that word. First, the world is changing.”
“Q I wholeheartedly agree with that last comment about the importance of competition, particularly in the supply chain. That is my experience as well, in terms of building out networks. I am just struggling to understand why Vodafone, Three and O2 said earlier that there were only two full-service suppliers in the UK, when Mavenir is saying to me that you could supply a 2G, 3G, 4G or 5G network within a year. I am struggling to understand how that works. Is it a question of the network operators not being prepared to commission you? Is it an issue of price, complexity or management? Why are you not considered a full supplier by the existing network operators in the UK? Stefano Cantarelli: Let me just address that initially before anyone else. We are a supplier in other places in the network, so they consider us a reliable supplier.”
“Q That is very helpful. I think you said that a site would connect not with fibre, but with something else. Stefano Cantarelli: Not only with fibre. The open RAN interface is such that you are not forced to use fibre only. You can also use internet connectivity. The internet is what you use when you are in a building.”
“Already, most of the core infrastructure of the MNOs is running on general-purpose hardware, such as Dell servers and so on, with software on top of it. The RAN is really the last one to be transformed, for the reason that I gave, and also because, as I said, the market has been dominated by some suppliers who have been providing hardware and software, because they work with better interfaces between the radio access component.”
“Q That is really helpful. What you are saying is that although you could deliver a full-service 2G, 3G, 4G or 5G network tomorrow, that is not what our mobile operators want. They want an incremental improvement from what they have to what they need to provide services. The cost is a real issue. The transition from 4G to 5G/open RAN is part of the challenge, and we need to understand better how the Government can support that. You talked about making it easier to roll out new open RAN sites. I am interested to know whether there are other ways in which the Government could support that. Stefano Cantarelli: I add that this transformation in the core infrastructure has already almost happened.”
“Thank you. That is very helpful. That makes me think that there are security issues arising from, for example, having our cloud infrastructure dominated by one vendor, such as Amazon Web Services. Those are perhaps future security issues that we need to look at. I now understand much better what you need to support your transition, so thank you very much for that.”
“If the Government suddenly say, “All components from supplier X must now be removed from the network because of x, y and z,” it is incumbent on the Government to have some funding to help people to do that and to ensure that that really does happen, because it could be a step too far if you have a lot of very small suppliers that do not have the resources of skills, time or money to do it. You need to think about that and about how you can ensure that they are not squeezed out of the network—this diverse network that we want—by those costs.”
“The more diversified your network, and the more small vendors there are, the harder it will be for them to maintain the level of scrutiny, record-keeping and general security that is required as their bits of the network develop and the interfaces they have with other bits of the network change over time. That is an area where the Government should consider giving help to people to cover those costs. I have said that audit is needed of the assets in the network. The costs of being audited and of dealing with audits are very high, and they are costs that small companies may not have the resources to meet.”
“You had four areas, and I think you have run through two of them in more detail. Could I ask you to summarise again the areas that you think are missing? In particular, could you talk a little bit more about the need for improved scrutiny? Could you just summarise that and then go into more detail on the ones where you have not yet? Dr Bennett: I said that the areas that needed to be covered were network architecture, which is the Bill’s focus, the security of the asset databases that make up the network, how to ensure security of the data passing over the network, the maintenance of security over time, and the operational costs and other impacts of compliance. I have touched on all of them, but perhaps not very much on the operational costs and impacts of compliance.”
“Q I am the shadow Minister for the Bill. Let me start by welcoming you and thanking you very much for your expert input. I particularly welcome you, Dr Bennett, for your expertise and the fact that you are the only female witness we have today—it is clear to me, as someone who worked in engineering for 20 years, that the sector’s gender balance has not improved. I hope that Parliament can do more to ensure more balance in witnesses in future. I have questions for both of you, but let me start with Dr Bennett. I was impressed by your structured list of things that are missing from the Bill, because we are here to scrutinise the Bill and see how we can improve it. I think you talked about the breadth of the security challenge and how this Bill, as it stands, might not meet the full breadth of it.”
“But those types of things are the types of applications that run over these very complex networks, and unintended consequences can happen as you change the network architecture. If those tier 3 suppliers and the people providing key applications over the network are not involved in this conversation at the CNI level with the top-level suppliers, all sorts of unintended things can happen. It is a question of how you make sure that you minimise the number of these unintended consequences and support people to realise what they need to do early on, so that they are not caught out by them.”
“The more of those you have, the more resilient your network might be on the one hand, because there are multiple parts, but on the other hand, the harder it is to maintain them adequately. We see some of these problems today in the decision to move the copper out of the network. Applications that are very important to many users, notably alarm signals, are ones that often assume they have an underlying network of a particular type, and if it is not there those applications do not work and they do not work suddenly. These types of things are very complicated but are actually very important for the end users. It may be an alarm that says an elderly person has fallen in their home; it may be an alarm that says your bank has been attacked by a criminal gang. Who knows what it may be?”
“Q To follow up briefly on that, I think what you are saying is that there might be a contradiction between the desire to have a more diverse supply chain, with more smaller players, and increased regulatory and other costs in this. With regard to network architecture and data flows, you make a very good point: we have been concerned about high-risk vendors, designated vendors and so on, but that will not address the issue of securing data flows. Do you have any thoughts, and are you suggesting that more thought needs to be put into that aspect of network security? Dr Bennett: I think most people would agree that the diversity of end points, of interfaces and of applications running over complex networks all pose security problem areas.”
“From a security perspective, we need to recognise that there are parts of the network that need to be kept secure, and there are parts of the network that are out of scope of that.”
“If you wanted to connect to a hospital, it would not be any good to have just one operator service and have only a quarter of the people served. You need all of them served, and that needs to be done affordably. We want to make sure that the partners of mobile operators, such as neutral hosts, are supported in legislation. It is also about recognising, as has been mentioned, the challenges of getting the hardware out. You can scale software just by selling it to more people, but hardware needs more feet on the streets and more deployers. We have to look at how we go about enabling more people to deploy mobile infrastructure into communities and industry, so that more people are aware of how it works, which means making the system simpler.”
