The streets of the capital were packed with placard-waving, slogan-singing demonstrators, intent on showing their vehement disapproval of the divisive American leader, in one of the biggest British protests in recent memory.

Organizers said 250,000 people took part in the protests in London and other cities across the country could see similar rallies, including Windsor, where Trump met with Queen Elizabeth.

Trump is a deeply unpopular figure in England, where he enjoys an 11 percent approval rating. Nearly 2 million Brits have signed on to a petition demanding that Trump not be honored with a state visit and someone may have been listening. His visit to the London this week was designated a working visit.

London Mayor Sadiq Kahn, who gave the go-ahead to fly a giant baby Trump balloon in the city, has defended the protesters. “The idea that we would park our rights and privileges and freedoms because it may cause offence to a U.S. president, I think people in London and the U.K. would find objectionable as indeed would Americans,” he said. “We should cherish the fact they’ve got the right.”
