Question to the Foreign, Commonwealth & Development Office:

To ask the Secretary of State for Foreign, Commonwealth and Development Affairs, with reference to paragraph 2 of Annex 1 of the document entitled UK/Mauritius: Agreement concerning the Chagos Archipelago including Diego Garcia (CS Mauritius No.1/2025), through what mechanism his Department will expeditiously inform the Government of Mauritius of an armed attack emanating from Naval Support Facility Diego Garcia; and what steps he will take to ensure that the disclosure of such information does not compromise operations.

Any notification will take place after the event and will not require the UK to divulge sensitive information. Agreement to inform a host nation is standard practice in many such arrangements, while the UN Charter itself has a requirement to notify the UN of military action taken in self-defence.
