Ministers are increasingly concerned President Donald Trump could cancel the deal to cede sovereignty of the Chagos Islands to Mauritius.

The President had previously derided the act as “stupid” and an “act of total weakness”.

In a phone call between Sir Keir Starmer and President Trump, the Prime Minister chose not to mention the treaty, leading to concerns among ministers that the US leader does not understand the deal, reports The Times.

President Trump’s British envoy Mark Burnett, initially briefed the President on its contents more than a year ago but diplomatic sources said more senior members of the administration had begun to assert themselves.

This includes Treasury Secretary Scott Bessent and US Ambassador in London Warren Stephens, who are among those who have been lobbied by Reform leader Nigel Farage or senior Conservatives.

Senior Conservatives have suggested their plan is to delay the legislation in the Lords for so long that it fails to pass before the end of the parliamentary session in May.

When pressed on if the deal was dead without American backing, a Downing Street spokesman said: “As the public would rightly expect, we’ve negotiated robust security provisions to protect the UK and the base for decades to come.”

Landlords across the country are continuing their plans to ban Labour MPs from their pubs as “the threshold has not been met” over plans to for pubs and music venues to get 15 per cent off their business rates bills

We’ll be hearing today from Andy Lennox, the Dorset landlord who started the ban, says rates reform was only one part of their demands and it was for the whole sector, not just pubs.

He says they stand in solidarity with wider Hospitality who have been excluded and thus will not be lifting the #NoLabourMP ban. Mr Lennox says, “the industry needs meaningful change, today’s announcement was not it.”
