More than 110,000 marched at Unite the Kingdom event in London, with 5,000 counter-protesters nearby

Police officers have been assaulted as they clashed with protesters at a “freedom of speech” festival led by the far-right activist Stephen Yaxley-Lennon, known as Tommy Robinson, Scotland Yard said.

More than 110,000 people gathered in central London for the event. Protesters marched from Southwark to Whitehall draped in the flag of St George and the union flag in what was called the “Unite the Kingdom” demo.

About 5,000 counter-protesters from trade unions and anti-fascist groups marched in a separate route in central London.

Scotland Yard said there had initially been “no incidents of note” as both groups marched towards Whitehall, but as the marches met one another on either end of the street, divided by metal barriers and lines of police, some supporters had tried to breach the line that was put in place to keep the groups apart.
