Question to the Ministry of Defence:

To ask the Secretary of State for Defence, (a) what role the National Security Council will have in the decision on whether to replace the Trident nuclear warhead, (b) whether that decision will be discussed by the full Cabinet and (c) whether Parliament will have a final vote on that decision.

As stated in the update to Parliament on 20 December 2017 the Dreadnought Programme (HCWS377), work is ongoing on warhead replacement options; I will continue to provide updates as appropriate.
