Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what the cost to the public purse was of running the UK-US military base on Diego Garcia in financial year 2023-24.

The direct cost to the Ministry of Defence (MOD) for running the UK element of the UK-US military base in the British Indian Ocean Territory in financial year 2023-24 was £3.8 million. This excludes minor costs incurred directly by, for example, visiting units or HQ elements in the UK. Any costs incurred by other Government Departments cannot be provided by the MOD.
