The London protest, known as the "Unite the Kingdom" march led by far-right activist Tommy Robinson, attracted an estimated attendance of between 110,000 and 150,000 people on September 13, 2025. This made it one of the largest far-right demonstrations in recent UK history. During the event, approximately 26 police officers were injured, and 24 to 25 arrests were made due to violent clashes between protesters and law enforcement. Additionally, around 5,000 counter-protesters took part in a separate anti-racism demonstration nearby. The event featured heavy police presence with about 1,000 officers deployed to keep order and separate the opposing groups.
