Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to paragraph 5 of Annex 1 of the document entitled UK/Mauritius: Agreement concerning the Chagos Archipelago including Diego Garcia (CS Mauritius No.1/2025), what estimate he has made of the cost of providing assistance to the Government of Mauritius to (a) monitor, (b) detect, and (c) adjudicate security risks and (d) conduct security reviews over the first ten years of the Agreement.

As set out in the new UK-Mauritius Strategic Partnership Framework, Mauritius and the United Kingdom will cooperate on matters relating to maritime security. Further engagement on the details of this cooperation with Mauritius is ongoing. Securing the future operation of the Base on Diego Garcia was the objective of the treaty with Mauritius and that will remain the objective in the work to operationalise the treaty.
