Already a few hundred Black Lives Matter protesters have gathered outside the US Embassy ready for today’s protest which starts at 2pm. Plenty of police already as well, many walking through chatting with the crowd @LBC

Police wouldn’t let the marching crowd get any closer to the US Embassy, so they took the knee, shouting things like ‘Black Lives Matter’ and ‘F*ck Boris, F*ck Trump.’ @LBC

Vauxhall Bridge blocked as protesters take the knee in the middle of it. Just over the river at the US Embassy you can see thousands have already gathered #BlackLivesMattter @LBC

The crowd are on the move, thousands marching north over Vauxhall Bridge - possibly heading to Westminster again @LBC

These little boys have made their own #BlackLivesMattter sign! Shouting ‘No Justice, No Peace’ from their window at the crowd as they march @LBC

Update: Police say 29 people were arrested in yesterday’s protests in central London.

The police officer who fell from her horse has had surgery in hospital, her injuries thankfully aren’t life threatening. @LBC

Some guys have turned up to protect the Winston Churchill statue themselves - as the #BlackLivesMattter crowd pass Parliament Square and head up to Downing Street again @LBC

“Boris Johnson’s A Racist” sung by thousands of protesters outside Downing St again @LBC

Protesters kneel shouting “Take A Knee” at the officers guarding Downing Street. Boos for the police when they don’t react

Bottles are hurled at the police coming out of Downing Street. The crowd surges forward and boos them @LBC

BREAKING: Police arrest a man who managed to climb over the barriers outside Downing Street, boos from the crowd and bottles thrown forwards but no other violence. @LBC

Smoke flares set off and lots more bottles being thrown forwards, a least one hits an officer

Something’s changed in the past hour, people have started really drifting away and the crowd have stopped chanting. It’s like a tiredness has settled
