May I say to my right hon. Friend that this statement smacks not only of promises kept, but of promises exceeded? I congratulate him on that. Does he accept that in an era when global cyber-attacks threaten our entire way of life—from the economy to the NHS—we need to spend more of our defence budget on assets that we cannot see as well as on updating our core assets, and that that needs to be clearly explained to the British people? In this war of the invisible enemy, does he believe that cyber doctrine has evolved to match our capabilities, especially on existential threats, in order to provide adequate deterrence?
My right hon. Friend is an expert on what he is talking about. I can tell him that the National Cyber Force is working on doctrine that is currently evolving, but we will deploy our cyber capabilities, as I am sure he and the House would expect, in accordance with international law to protect the British public and our citizens.
