The "Unite the Kingdom" march held in London in September 2025 drew an estimated attendance of between 110,000 and 150,000 people according to Metropolitan Police estimates. This event was one of the largest far-right demonstrations in recent UK history, organized by the activist Tommy Robinson. Some far-right supporters initially claimed there were as many as three million protesters, but official police figures significantly disputed that number. The event saw heightened tensions and clashes with police, leading to injuries among officers and multiple arrests.
