Theresa May has been accused of trying to stop Donald Trump from meeting Nigel Farage is on his visit to the UK next week.

A Whitehall source said a ban on a meeting with Mr Farage, the former UK Independence Party leader, is a red line for 10 Downing Street in the negotiations about the visit to the UK on Friday next week.

The source said Number 10 has made it clear that the US President "must not meet Farage" in the talks over the itinerary.

US officials were in London last week to try to nail down the plans for the trip which will see Mr Trump and his wife Melania meet with the Queen and the Duke of Edinburgh.

Mr Farage added that he had been told the UK Government had made it clear that it did not want Mr Trump to meet with him during his visit "through the normal protocol channels".

He said: "I understand that through the normal protocol channels established between [the countries] ahead of a visit that they are very keen - almost paranoid I was told - that he [Trump] doesn't meet me.”
