Donald Trump’s long-awaited state visit to the UK is expected to be announced on Tuesday, sources have said.

The US President’s official trip could be scheduled for early June, according to reports, and follows a working visit he made to Britain last summer with his wife Melania.

Prime Minister Theresa May was widely criticised for offering such a controversial figure the honour of a state visit just days into his presidency when she met Mr Trump for the first time in the White House in January 2017.

The state visit was expected that year but no date was set.

The US leader’s 2018 trip to the UK had many of the trappings of a state visit, including a meeting with the Queen at Windsor Castle.

The president’s visit is likely to draw demonstrations in the same way as his July 2018 trip and security is expected to be high.

The organisation Stand Up To Trump said campaigners had pledged to mobilise huge numbers in response to rumours of a state visit.

Member Sabby Dhalu claimed the US leader is “the world’s number one racist, warmonger and misogynist”.

“A formal state visit to Britain in June must be met with widespread opposition,” she said. “All those that value peace and hope for a better world for the many must take to the streets and say clearly that Donald Trump is not welcome here.”

Mr Trump reportedly told Mrs May in 2017 that he would not come to Britain for his state visit until he is sure of getting a “better reception”.

The president will be hosted by the Queen at either Buckingham Palace or Windsor Castle and the visit is likely to follow the traditional format of an official open-air welcome, featuring prestigious British regiments, lunch with the Queen and a state banquet.

State visits normally last three days, and once the ceremonial elements with the Queen have been completed, visiting heads of state follow an itinerary that reflects their own interests and political aims.

Around the time of the visit, Mr Trump is reportedly due to travel to Europe and attend commemorations marking the 75th anniversary of the D-Day landings.

House of Commons Speaker John Bercow said a request for a state visit from the US leader would be “considered in the usual way”, but did not say whether a request had yet been received.

A spokeswoman for the Speaker’s Office said: “Should a request be made to address the Houses of Parliament, it will be considered in the usual way.”
