Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to Annex 1, Clause 2, of the UK/Mauritius: Agreement concerning the Chagos Archipelago including Diego Garcia [CS Mauritius No.1/2025], what protections are in place to ensure that Mauritius does not pass on information relating to an armed attack to any (a) third parties and (b) other nations.

Article 3(2) of the Treaty states that Mauritius cannot undermine, prejudice or otherwise interfere with the long-term, secure and effective operation of the military base on Diego Garcia, and that Mauritius shall cooperate to that end. This will ensure that military operations are not compromised in any way. In addition, I refer the hon. Member to the answer I gave him on 12 June 2025 to Question 57298, any notification to Mauritius will take place after the event and will not require the UK to divulge sensitive information.
