US diplomats have dropped plans for Donald Trump to conduct a visit to Britain in January amid a war of words between the two countries’ leaders.

Mr Trump, the US president, had been pencilled in for a ‘working visit’ in the first month of 2018 to formally open America’s new London embassy.

The trip, a scaled down version of a state visit with no meeting with the Queen, was intended to allow Mr Trump to come to the UK while avoiding the mass protests a full state visit would likely trigger.

However, The Telegraph can reveal that the trip has been pushed into the long grass, with no new date in the diary picked.

A senior US diplomat said: "The idea of a visit has obviously been floated, but not December and not January. I would not expect a Trump visit in January."

It comes with relations between Theresa May and Mr Trump deteriorating in a public spat over the US president’s tweeting of videos posted by Britain First, a far-Right group.
