Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what information would need to be passed to Mauritius in the event of an armed attack on a third State directly emanating from the military base on Diego Garcia.

It is standard practice for basing arrangements to include an agreement to inform a host nation about military action from their territory. Additionally, the UN Charter has a requirement to notify the UN of military action taken in self-defence. Any notification to Mauritius will take place after the event and will not require the UK to divulge sensitive information. The United Kingdom will inform Mauritius through normal diplomatic channels.
