Caroline Lucas asked the Secretary of State for Defence “with reference to the United Kingdom’s Future Nuclear Deterrent: The Dreadnought Programme 2017 Update to Parliament published 20 December 2017, what the procedure will be for taking the decision on replacing the warhead in this Parliament; if she will make it her policy for there to be a vote in Parliament on the decision; and if she will make a statement.”

Penny Mordaunt, Secretary of State for Defence, responded, “As set out in the 2017 and 2018 updates to Parliament, work is continuing to refine options and technical solutions to inform the Government’s decision on replacing the warhead. We will continue to provide updates as appropriate.”
