Thousands of people are expected to descend upon the streets of London in protest at Donald Trump’s unprecedented second state visit.
The US president arrives in Britain on Tuesday night for a two-day stay, during which time he and his wife Melania will meet King Charles and Sir Keir Starmer, the Prime Minister.
His Majesty will host Mr Trump and the First Lady on Wednesday at Windsor Castle in Berkshire, before the trip continues on Thursday at the PM’s Chequers country residence in Buckinghamshire.
Trade, Ukraine and Gaza are set to dominate talks between Mr Trump and Sir Keir. The pair may also discuss the recent dismissal of Lord Mandleson, the former British ambassador to Washington, over his past relationship with convicted paedophile Jeffrey Epstein.
Although Mr Trump will not visit Parliament, which is currently in recess for the party conferences, campaigners vowed to demonstrate against what they called “our government’s choice to honour a man who is violating human rights in the United States and around the world”.
The Stop Trump Coalition — which is composed of more than 50 trade unions, charities and interest groups — will gather in Portland Place near the BBC’s New Broadcasting House at 2pm on Wednesday before marching towards Parliament Square.
It will also feature speeches from the likes of new Green Party leader and City Hall member Zack Polanski, as well as former Labour leader and Islington North MP Jeremy Corbyn.
Up to 150,000 people turned out for the Tommy Robinson-organised Unite The Kingdom rally on Saturday, far exceeding the estimates of organisers.
And approximately 250,000 people marched across the capital to protest Mr Trump’s “working trip” in 2018, featuring a 20ft inflatable caricature of the president.
Zoe Gardner, a migration policy specialist, claimed Mr Trump was “opening the door to global fascism” and said his visit would drag Britain “further into the abyss”.
Yesterday, the largest far-right protest in UK history marched through London, led by racist Tommy Robinson.

In a video posted by the coalition, featuring an AI-generated dystopian Britain ruled by far-Right paramilitaries, Ms Gardner said: “There is a darkness coming. It has already swallowed America and now it is coming for us too.”
But Chris Philp, the shadow home secretary, told The Daily Telegraph: “This is hysterical scaremongering by people who are clearly unhinged. The idea that welcoming the democratically elected leader of our closest ally could open the door to some sort of fascism is obviously absurd.
“These people need to reconnect with reality. This sort of stuff risks inflaming tensions and inciting violent mobs.”
It is understood that Scotland Yard has a “significant policing operation” in place in the city, which comes just days after Charlie Kirk, a staunch ally of Mr Trump, was assassinated in Utah.
Nearly 10,000 officers from across the UK, including armed response, were needed to cover Mr Trump’s last state visit.
Meanwhile, Thames Valley Police have said officers will be ready to respond to a potential “very high threat level”, with plans to make the town secure from the skies, streets and River Thames.
Asked whether the death of Kirk, 31, on Thursday had influenced the policing operation for the visit, Assistant Chief Constable Christian Bunt said: “We are constantly keeping under review our approach to these operations. We’re doing that on a daily basis, right through the planning phase.
“I’m very content that we have planned a very comprehensive policing and security operation that has taken into consideration just about every eventuality of what could happen.”
Mr Trump is likely to be accompanied by a motorcade, including his armoured Cadillac limousine dubbed The Beast, after touching down at London Stansted Airport in Air Force One.
As well as his wife, Mr Trump will be joined by secretary of state Marco Rubio, treasury secretary Scott Bessent, commerce secretary Robert Lutnick, agriculture secretary Brooke Rollins and special envoy Steve Witkoff.
