"Our position on the state visit has not changed? an offer has been extended and President Trump has accepted".
London's mayor Sadiq Khan said he was "not sure it is appropriate for our government to roll out the red carpet" for Trump, but was reported to be open to a working visit.
Speaking during his daily LBC talk show, the former United Kingdom politician said: "Everywhere he goes he is given a full state visit and yet, with this country, it has been decided that when he will come in 2018 he will not go to Buckingham Palace for dinner".
The Queen usually receives two heads of state per year - most recently Spain's King Felipe - and has hosted 111 State Visits throughout her reign.
A spokesperson for British Prime Minister Theresa May said Trump had accepted an invite for a state visit, but that her office was not aware of any discussions relating to a separate working visit.
Officials on both sides of the Atlantic tried to downplay this change of plans, claiming a full-fledged state visit was still on the cards.
There have already been protests against Trump across Britain. Another 40,000 marched in London in February.
There was also a public backlash, with nearly two million people signing a petition saying the U.S. president's "well documented misogyny and vulgarity" disqualified him from an audience with the Queen.
Maz Saleem said, "We will be prepared to organise mass demonstrations against his visit whatever its status".
At a Stand Up To Racism fringe meeting at Labour Party conference Tottenham MP David Lammy said he would join protests if Trump came to Britain.
Donald Trump won't be getting the royal treatment. That needs to be brought on to the streets when he comes here.
