Welcome to this live blog, where we’ll be bringing you the latest updates from this breaking news incident near Downing Street.
A St George’s Day event is taking place on Richmond Terrace, off Whitehall, this afternoon. The Metropolitan Police have said they believe groups attending the event will include far-right groups and groups linked to football clubs travelling into London from across the UK.
However, while certain orders have been issued for the event, fights have already broken out, according to posts on social media.
The Metropolitan Police have confirmed that while the event is not due to start for an hour, officers are already dealing with disorder.
They said: “There is an area allocated for this event in Richmond Terrace. This group went past it and continued up Whitehall.
“When officers formed a cordon and asked the group to turn round, they reacted by violently forcing their way through. Mounted officers intervened with horses to restore the cordon.”
