Tens of thousands of people have taken to the streets in protest at US president donald trump’s visit to the uk. Treasurers of the "stop trump" initiative even spoke of "at least 250,000" demonstrators in london alone. There were also demos in other cities such as belfast and windsor.

Several protest marches went through the center of london to the government district between parliament and trafalgar square. Police said this afternoon that the site had reached capacity. Several helicopters circled over the city center.
