Boris Johnson and Liz Truss both lobbied Donald Trump to block the UK’s plan to hand over the Chagos Islands to Mauritius, it has been reported, after the US president threw the deal into fresh doubt this week.
Mr Trump earlier this week urged Sir Keir Starmer not to “give away Diego Garcia” – an island on the archipelago which is home to a joint UK-US military base – despite Washington signalling its official backing for the deal on Tuesday.
