  It is a pleasure to follow the hon. Member for Newcastle upon Tyne Central and West (Dame Chi Onwurah), who has brought tremendous expertise to this debate. In my previous role overseeing national resilience and cross-Government co-ordination of national security threats, cyber-security was probably the one area that caused me the greatest number of sleepless nights. There has been a lot of talk in recent months and years about the increased need to defend the realm and the steps that need to be taken to address the defence of the realm. We all know from past experience that the first line of any attack on the defence of the realm is highly likely to be through cyber-attacks. Indeed, in a completely different context, we need only to look at the public comments made by the President of the United States a couple of days ago about the first steps that the United States took in its intervention in Venezuela: he talked about the United States’ capability to knock out the power supply there. If we look at our adversaries, particularly Russia, North Korea and Iran, we can see that they are actively inculcating and encouraging environments in which cyber-attacks can be planned and take place. Whether that is done explicitly by private sector individuals or with the connivance of the state, a deliberate grey zone is created, with the desire to increase knowledge of cyber-risks to the United Kingdom and our allies, and to carry out penetrative attacks to that effect. We are likely to see this grey zone warfare continue to increase as a result of the actions that we see in Ukraine and elsewhere. We just have to look at our own experience. Many hon. Members have made the point that the initial attack on JLR rapidly cascaded and affected many others in the supply chain. From the Government’s own research and testing—this is in the public domain—one sees that a cyber-attack can rapidly cascade into other areas. For example, when we test the impact of a cyber-attack on our electricity system, it rapidly cascades into our water system, which is dependent on electricity. Clearly, it also rapidly cascades into our transport system. Before long, a small cyber-attack becomes a very, very large cyber-attack. In common with all other advanced countries, the United Kingdom is highly exposed to cyber-attacks—a point that I made repeatedly from the Dispatch Box. I welcome this legislation and the steps that the Minister has outlined today, but I gently caution against what he said. I do not think it was his intention, but he said that this legislation will fix the cyber-security problem. It will not fix the cyber-security problem. No single piece of legislation is ever going to fix the cyber-security problem, nor is this a question of good guys and bad guys or of, “The last Government did nothing, and this Government are doing something.” Each Government must have a fresh look at the challenges of cyber-security, and take necessary and proportionate steps to address the risks.
