Question to the Foreign, Commonwealth & Development Office:

To ask the Secretary of State for Foreign, Commonwealth and Development Affairs, if she will publish official communications from the US State Department sent in March 2025 on the legal premise for transferring the sovereignty of the Chagos Islands to Mauritius.

The Government's legal position was set out on 22 May 2025 when the treaty was signed and can be found here: https://www.gov.uk/government/news/uk-secures-future-of-vital-diego-garcia-military-base-to-protect-national-security

I would also refer the Rt Hon Member to the statement made by US Secretary of State Marco Rubio on the same day, which said: "The U.S. welcomes the historic agreement between the UK and Mauritius on the future of the Chagos Archipelago. This agreement secures the long-term, stable, and effective operation of the joint U.S.-UK military facility at Diego Garcia, which is critical to regional and global security. We value both parties' dedication. The U.S. looks forward to our continued joint work to ensure the success of our shared operations."
