The incoming Donald Trump administration has reacted with ‘outright hostility’ to Labour’s deal to hand over control of the Chagos Islands, Nigel Farage warned today.

The Reform UK leader, a top cheerleader for the hard right Republican, branded a deal to give the British Indian Ocean Territory to Mauritius ‘an enormous mistake’.

And he suggested in the Commons that the deal – which is due to be signed off next year, may never go ahead due to the opposition of the White House.

David Lammy last month announced the archipelago will be handed over to Mauritius, with a 99-year lease on the Diego Garcia airbase.

But it has been widely branded a ‘surrender’ of UK territory to a nation 1,300 miles away.

Mr Farage, who has made repeated visits to the US either side of the November 5 election, told the Commons: ‘There is outright hostility to this deal.’

But he was earlier mocked for his support for Trump, after trying to get the chamber to congratulate him on his election win at Prime minister’s Questions. Replying to his request, Sir Keir said:

The Prime Minister replied: ‘I’m glad to see (Mr Farage) making a rare appearance back here in Britain, he spends so much time in America recently, I was half expecting to see him on the immigration statistics.’

He added: ‘I did congratulate the incoming President last week, we will work with him.’
