Theresa May is facing a growing Cabinet backlash over her decision to dismiss Nigel Farage despite him being the only British politician to meet with Donald Trump since his victory.

The Telegraph understands a number of members of the Cabinet and other Government ministers believe the Prime Minister's allies have made a mistake by referring to Mr Farage as an “irrelevance”.

One Cabinet source also accused Downing Street of having "made no plan" for a Trump victory, despite Government claims that officials have for months been holding talks with members of his inner-circle.

Mrs May has made clear that none of her ministers will be allowed to speak to Mr Farage, the interim Ukip leader, despite his close links to Mr Trump.

Mr Farage on Saturday spent nearly one hour with the president-elect at Trump Tower in New York.
