Question to the Ministry of Defence:

To ask the Secretary of State for Defence, whether the Defence Investment Plan will report based on a cost envelope of (a) 2.5%, (b) 3% or (c) 3.5% of GDP on defence expenditure.

The Defence Investment Plan will set out how the MOD will deliver the vision of the Strategic Defence Review within the MOD's share of the Government's commitment to spending 2.6% of GDP on defence by 2027, and 3% of GDP in the next Parliament as fiscal and economic conditions allow.
