Question to the Ministry of Defence:

To ask the Secretary of State for Defence, whether Article 4 of the UK/Mauritius: Agreement concerning the Chagos Archipelago including Diego Garcia [CS Mauritius No.1/2025] would require the Government to block the US from using the Base on Diego Garcia if the Attorney General ruled that its use would not be in compliance with international law.

All UK overseas bases are operated in accordance with our obligations under international law. This includes Diego Garcia. Article 4 of the treaty reflects the existing UK position.
