Question to the Ministry of Defence:

To ask the Secretary of State for Defence, whether Parliament will be asked to vote on a decision to replace the warheads used for the successor nuclear weapon programme.

As stated in paragraph 4.72 of the 2015 Strategic Defence and Security Review: "Work continues to determine the optimum life of the UK's existing nuclear warhead stockpile and the range of replacement options. A replacement warhead is not required until at least the late 2030s, possibly later. Given lead times, however, a decision on replacing the warhead may be required in this Parliament or early in the next." The Government will inform Parliament of its intended approach in due course.
