Mr Tanmanjeet Singh Dhesi

I thank the Minister for his response, and your good self, Mr Speaker, for kindly granting the urgent question. Following the report in The Sunday Times that the Ministry of Defence is looking to purchase American fighter jets that are capable of deploying tactical nuclear weapons, it is essential that the House gets clarity on the Government’s nuclear deterrent policy—an issue of critical national importance. How have the media got hold of such sensitive information on future nuclear deterrent plans, and what steps are the Government taking to investigate the leak? If the Government are pursuing an air-launched tactical nuclear capability, that is a huge deal. It would represent a significant shift in the UK’s nuclear posture. Indeed, it would be the UK’s most significant defence expansion since the cold war. This raises serious concerns about our sovereignty when it comes to nuclear weapons, about strategic coherence with our current doctrine, and about the principle of continuous at-sea deterrence. Despite the defence nuclear enterprise accounting for around 20% of the defence budget, it remains largely outside meaningful parliamentary scrutiny, including by our Defence Committee. This must change, so will my hon. Friend the Minister explain how Parliament will be enabled to scrutinise changes to the UK’s nuclear programmes? Have discussions taken place with the US, and what role would it play in this capability? Will the Minister confirm that the UK will retain full operational control over any nuclear weapons? Given that tactical nuclear weapons lower the threshold for nuclear weapon use, what assessment has been made of the risks of escalation? Will the Minister confirm that only the Prime Minister would have authority to use them, and only in extreme self-defence? Finally, has there been consultation with NATO allies on this potential shift? Decisions of this magnitude must be transparent. The future of our nuclear deterrent must be based on clarity, credibility and, above all, British control.
