Question to the Ministry of Defence:

To ask His Majesty's Government what assessment they have made of the UK's resilience against nuclear weapons.

The United Kingdom’s (UK) independent nuclear deterrent exists to deter the most extreme threats to our national security and way of life, which cannot be deterred by other means.

His Majesty’s Government will continue to keep our nuclear posture under constant review in light of the international security environment and the actions of potential adversaries. The UK will maintain the capability required to impose costs on an adversary that would far outweigh the benefits they could hope to achieve should they threaten our, or our Allies’, security.
