Question to the Foreign, Commonwealth & Development Office:

To ask the Secretary of State for Foreign, Commonwealth and Development Affairs, pursuant to the answer of 26 March 2025 to Question 39405 on British Indian Ocean Territory: Sovereignty, on what date he plans to (a) sign the proposed treaty with Mauritius and (b) present that treaty to Parliament.

Both sides remain committed to concluding a deal on the future of the Chagos Archipelago which protects the long-term effective operation of the joint UK-US base on Diego Garcia.  We continue to engage with Mauritius and are not going to provide a running commentary on the details.
