Tommy Robinson march - LIVE: Police make arrests as thousands of Robinson supporters join protest in London

An activist has stressed to the crowd and press in central London that they are not here “just for the Kaba family”, but for all “grieving” families who are “bereaved at the hands of the state”.

She spoke of “collective grief”, “devastation” and “disappointment”, adding: “We have each other. We are strong. We are powerful.”

The speaker finished by leading a chant of “we believe that we will win” and “the people united will never be defeated”.

A counter-protest organised by Stand Up to Racism, has called on its supporters to “take to the streets” in a “massive anti-fascist demonstration”.

The march from Trafalgar Square to Downing Street has now started.

The front of the group is holding a banner which reads: “United Families and Friends Campaign. No more deaths in custody”.

Activists are holding signs reading “No justice”, “no one forgotten, nothing forgiven” and “no to hatred, no to fascism”.

Protesters are also holding images of people they say died in custody.

The Stand Up To Racism counter-protest is forming up in Regent Street St James’s.

The march is set to begin at 1pm, heading up and around Piccadilly Circus, down Haymarket and round into the top of Whitehall.

The assembly area of the far-right march has been adjusted after attendees set off from Victoria Station over an hour early.

The Met Police said: “The ‘Uniting the Kingdom’ march is forming up in Victoria Street. Working with the event organisers we have moved the forming up area north to the junction with Buckingham Gate to help keep the area around the station clear. The march will set off at 12.30pm.”

The extremist far-right march has been halted temporarilynafter setting off over an hour early.
