A fundamental part of the conversations about the strategic defence review that Lord Robertson and the review team have been having since the Labour Government came to power is how we reinforce the concept of deterrence, and why the concept of deterrence is so important to our security. Our armed forces—some of the best in the world—have capabilities that should deter any aggression, and we will be further enhancing that through the measures set out in the strategic defence review, as the Defence Secretary will announce shortly. We want to deter aggression but, if necessary, we need to have the capabilities to defeat it, and that is what the strategic defence review, which will be announced shortly, will detail to the House.

As it was this issue that brought me into politics many decades ago, it is an absolute pleasure to hear the full-throated commitment of both the Government and the Liberal Democrats to the strategic nuclear deterrent. If the future of the American commitment to NATO were not in doubt, we would not need to think about tactical nuclear weapons ourselves, because that role has always been fulfilled by US tactical nuclear weapons allocated to the defence of NATO. Will the Minister assure the House that we have sufficient confidence in the willingness of the United States, despite the present Administration’s attitude to NATO, that the co-operation that we need for the future of our strategic nuclear deterrent is not in doubt?

I can indeed. The defence partnership we have with the United States, particularly on nuclear deterrence, is a strong one. We know that President Trump and the US Defence Secretary, Pete Hegseth, have reaffirmed their support for article 5 of the NATO treaty. As we build towards the NATO summit in The Hague, the UK will set out not only how we plan further to enhance our deterrence, but how we plan to ensure that collectively, across the NATO alliance, we are more lethal and more able to deter. The reason why that additional deterrence is necessary is the increased threats that we face as a nation, both conventional and cyber-threats, and increased nuclear threats.
