Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what progress his Department made on meeting the target in the Strategic Defence and Security Review, published in 2010, to reduce the UK's nuclear warhead stockpile ceiling from not more than 225 to not more than 180 by the mid 2020s.

As announced in the Integrated Review of Security, Defence, Development and Foreign Policy, published on 16 March 2021, the UK will move to an overall nuclear weapon stockpile of no more than 260 warheads. I am withholding further details on the size of the stockpile for the purposes of safeguarding national security.
