Question to the Foreign, Commonwealth & Development Office:

To ask the Secretary of State for Foreign, Commonwealth and Development Affairs, what estimate she has made of the cost of the public purse of the Diego Garcia Military Base and British Indian Ocean Territory Bill.

I refer the Hon Member to the details of the forecast cost at the time, and duration of the treaty set out in the Explanatory Memorandum published on 22 May 2025, and to the extensive discussion of all these issues and methodologies that has subsequently taken place during the passage of the Bill.
