Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to Annex 1, Clause 7, of the UK/Mauritius: Agreement concerning the Chagos Archipelago including Diego Garcia [CS Mauritius No.1/2025], which activities his Department considers risk conflicting with the obligations in Article 3(2)(b).

As set out in Annex 1, Clause 7 of the Treaty, the UK holds the right to notify Mauritius about any activity that is seen as potentially undermining, prejudicing or otherwise interfering with the long-term, secure and effective operation of the base on Diego Garcia. Mauritius would then commence a Security Review in respect of these activities . This means that the UK will have an effective veto over any activity that presents a clear and direct threat to the base on Diego Garcia. There is no limit to the scope of activities considered under this condition.
