Mr. Khan, the mayor, has endorsed the march.
“Londoners have always chosen hope over fear, unity over division, and have approached challenges with optimism rather than despair,” Mr. Khan wrote in the London Evening Standard. “Time and again our city has chosen hope over fear and unity over division. So now more than ever we have a responsibility to stand up for our values and ensure our voice is heard around the world. We want and need the U.S. to stand by our side as a beacon of tolerance, openness and respect — as it always has before.”
Owen Jones, a left-wing journalist and lead organizer of Britain’s “Stop Trump” protests, said on Wednesday: “We need to show that we abhor everything that Trump represents: the bigotry, racism, anti-Muslim prejudice and misogyny.”
On Friday morning, some protesters plan to follow Mr. Trump to Chequers, the country house of the prime minister, where he and Mrs. May will hold talks on security and trade issues.
The main demonstration, “Together Against Trump,” is planned in London for 2 p.m. on Friday, with the giant balloon. Muslim groups also plan to march in protest after Friday Prayer. The police expect more than 100,000 demonstrators.
On Saturday, supporters plan to march from the United States Embassy to Whitehall, where government offices, including those of the prime minister, are concentrated. The Metropolitan Police said on Thursday that they were imposing restrictions on that rally and a counter-demonstration “in order to prevent serious disorder and disruption to Londoners.”
At Windsor Castle, west of London, where Mr. Trump and his wife are to meet Queen Elizabeth II, protests are expected. The president and the first lady will then travel to the Trump Turnberry golf resort in Scotland, where they will spend the weekend. But it will hardly be peaceful.
“Donald Trump is not welcome here,” the Scottish Labour and Scottish Green parties said in a statement. “The horrific scenes at the Mexican border are a repudiation of decent human values. Caging children like animals is barbaric. We cannot roll out the red carpet for a U.S. president that treats human beings this way.”
