Disorder at a St George's Day gathering at Whitehall

Disorder broke out at a St George's Day gathering at Whitehall. The Metropolitan Police shared a video of the chaos writing, "The event is not due to start for an hour and regrettably officers are already dealing with disorder. 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."
