Donald Trump has branded the UK's decision to hand the Chagos Islands to Mauritius as an "act of total weakness". In a Truth Social post, he sarcastically referred to the UK as a "brilliant" NATO ally and said the policy towards the islands was one of "GREAT STUPIDITY". The post follows Sir Keir Starmer's address to the nation on Monday, in which he criticised the US president's demand to take control of Greenland.
