Tommy Robinson, a British far-right activist known for anti-Islam campaigning, recently organized a massive protest called the "Unite the Kingdom" rally in London on September 13, 2025. The rally drew an estimated crowd of between 110,000 to 150,000 people, making it one of the UK's largest right-wing demonstrations in recent years. The protest was billed as a demonstration for free speech and against immigration. During the event, violence erupted as a small group of Robinson's supporters clashed with the police, resulting in at least 26 police officers being injured, some seriously, and about 25 people arrested for violent disorder and assault. The police had to deal with clashes between Robinson's supporters and counter-demonstrators. The march was marked by nationalist and anti-immigration rhetoric, and featured support from notable far-right figures and online support from Elon Musk. Robinson himself has a long history of far-right activism, multiple convictions, and controversies including jail terms. He has also received funding and support from right-wing groups in the US and Canada. The latest rally reflects ongoing debates and tensions in the UK surrounding migration and national identity. In summary, what recently happened with Tommy Robinson is that he led a large and contentious far-right march in London that turned violent with injuries to police and arrests, drawing national and international attention to his activist role and its divisive impact in the UK.
