Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to recommendation 32 of the Strategic Defence Review: Making Britain Safer: secure at home, strong abroad, published on 2 June 2025, which government departments will participate in the progress review of the National Endeavour for delivering the UK’s nuclear deterrent.

The National Endeavour to maintain and renew the United Kingdom’s nuclear deterrent is a whole of Government effort. The Ministry of Defence works closely with other Government departments, including the Cabinet Office, His Majesty’s Treasury, the Ministry for Housing, Communities and Local Government and the Department for Energy Security and Net Zero, to ensure its effective delivery. The National Security Council (Nuclear) remains committed to regularly reviewing progress on the National Endeavour. It receives comprehensive updates on delivery at least twice each year, with involvement from all relevant Departments.
