Question to the Foreign, Commonwealth & Development Office:

To ask the Secretary of State for Foreign, Commonwealth and Development Affairs, pursuant to the Answer of 15 July 2025 to Question 64734 on Diego Garcia: Military Bases, if he will place a copy in the House of Commons Library of the terms of the lease extension clauses that were agreed at the time that he made his statement to the House of Commons on 7 October 2024; and if he will publish an explanatory note for the changes made in the version of the Treaty signed on 22 May 2025.

We have been clear and consistent regarding the duration of the treaty. The treaty will last for an initial 99 years and may be extended for a further 40 years (and beyond) by agreement between the UK and Mauritius.

Even if no agreement is reached, the UK will have the right to first refusal on the use of Diego Garcia which, if exercised, would prevent the use of the base by any other party.
