Question to the Ministry of Defence:

To ask the Secretary of State for Defence, pursuant to the Answer of 4 June 2025 to Question 57372 on Chagos Islands: Sovereignty, what the costs were to his Department of the Agreement concerning the Chagos Archipelago including Diego Garcia.

As set out by the Secretary of State in his statement on 22 May 2025, the Agreement is at a cost of less than 0.2% of the annual defence budget and secures a base which is vital for UK national security for over a century. It represents good value for UK taxpayers.

A bill to implement the Treaty was introduced by the Government to the House of Commons on 15 July 2025.
