"Donald Trump likes to pose as an global tough guy, but it looks like he's too scared to face protesters in London", the group Stand Up to Trump declared in a statement, alluding to the US president's reported plans to steer clear of the streets of London.
"The protest against Trump will be a real celebration of the diversity that we love in the United Kingdom - and will give a strong signal that his message of hate and division is not welcome in this country".
Mr Trump raised eyebrows when he went out of his way to praise Boris Johnson after resigning as foreign secretary, while insisting it was up to the British people whether Mrs May remained in office or not.

The Republicans Overseas UK group expects up to 100 people to attend its event on Friday evening to show there are people who are happy about the trip, chairwoman Sarah Elliott said.

"But from the public, the welcome will be far from warm", he added saying there would be protests across the country against Trump's "abysmal record on human rights, his repugnant attitude towards women and his disgusting treatment of minorities".
Meanwhile, London Mayor Sadiq Khan has granted permission for a giant inflatable figure depicting Mr Trump as a baby to fly over Westminster for two hours on the second day of the president's visit.
The two leaders will hold talks at the Prime Minister's country residence of Chequers where Russia, Brexit and the Middle East will top the agenda.
On the final day of his visit, he is likely to head for the golf course - Turnberry - which he owns in Scotland, before he jets back to the United States.
