THE Metropolitan Police has made four arrests at a far-right march and counter-protest in London.

Thousands of Tommy Robinson supporters gathered in central London on Saturday for a planned protest following the English Defence League co-founder’s arrest on Friday.

The far-right demonstration attracted a sizable counter-protest from Stand Up to Racism activists.

Police say two people have been arrested at the far-right "Uniting the Kingdom" march, one for a racially aggravated public order offence and another for a breach of the Public Order Act conditions in place.

Officers arrested a counter-protestor for common assault following unrest at the Stand Up to Racism demonstration.

A further arrest was made after an officer was assaulted when a group tried to push through a cordon.

Robinson, 41, real name Stephen Yaxley-Lennon, was charged on Friday for failing to provide his mobile phone password to police under schedule 7 of the Terrorism Act 2000, Kent police said.

Robinson is also accused of being in contempt of court after the airing of a film at a protest in Trafalgar Square in July.

He was remanded before a hearing at Woolwich crown court on Monday concerning allegations that he breached a 2021 high court order barring him from repeating libellous allegations against a refugee who successfully sued him.
