Question to the Ministry of Defence:
To ask the Secretary of State for Defence, what estimate he has made of the cost to the public purse of the proposed expansion of the cap on the UK's stockpile of nuclear warheads.
As announced in the Integrated Review the UK will move to an overall nuclear weapon stockpile of no more than 260 warheads. This is a stockpile ceiling, not a target, and we will remain deliberately ambiguous about the exact number of warheads in our stockpile to avoid simplifying the calculations of potential adversaries, similarly the precise costs associated with the size of the stockpile will be withheld for National Security reasons.
