Postponing deal has harmed UK's reputation, diplomat sayspublished at 14:12 British Summer Time 22 May
Let's bring you some more of what was heard in court now.
Harriet Mathews, director general for Africa, the Americas and Overseas Territories at the Foreign Commonwealth and Development Office, told the High Court that the overnight injunction had "caused harm to the UK's reputation" with Mauritius, the US and others who use the Diego Garcia military base or have interest in its use.
She writes in her witness statement that as a result the UK is "expending significant diplomatic effort to manage these implications and to reassure Mauritius and our partners that we are still committed to g the agreement".
