The Tommy Robinson-organized "Unite the Kingdom" march held in London in September 2025 drew an estimated attendance of around 110,000 to 150,000 people, according to multiple reports from the Metropolitan Police and news sources. The event became one of the UK's largest right-wing demonstrations in recent history, with a notably large crowd that exceeded initial expectations. During the march, clashes occurred between some protesters and police, resulting in injuries to 26 officers and at least 25 arrests. A separate counter-protest of about 5,000 people was held nearby.
