Question to the Ministry of Defence:

To ask the Secretary of State for Defence, when he will make a decision on the number of F-35 aircraft his Department will procure.

Decisions on future numbers and aircraft variants will be taken at the relevant time to ensure the most appropriate capability for our Armed Forces and best value for money.

The Government is currently undertaking the deepest review of Britain's security, defence and foreign policy since the end of the Cold War. The outcome of this review will inform future procurement across the equipment spectrum.
