The march organized by Tommy Robinson on September 13, 2025, in central London had between 110,000 and 150,000 people in attendance according to police estimates. This event, called the "Unite the Kingdom" rally, was one of the largest right-wing demonstrations in the UK. There were also around 5,000 counter-protesters present at the event. The large crowd exceeded initial expectations and caused significant police deployment and some violent incidents during the event.
