Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to the £72.3 billion allocated in the Defence and Equipment Plan 2013 supporting existing in-service equipment, how much of that allocation is devoted to (a) nuclear propulsion and (b) nuclear weapons.

Of the £72.3 billion referred to in the 2013 Equipment Plan we plan to allocate to the support of in-service equipment over the next decade, £1.6 billion is for nuclear propulsion and £13.0 billion for maintaining the Trident Strategic Weapons System, including costs associated with the nuclear warhead.
