More than 100,000 participants attended a rally in central London organized by far-right activist Tommy Robinson, known for anti-immigration views, with a simultaneous counter-protest by around 5,000 anti-racism supporters from Stand Up To Racism. The Metropolitan Police reported nine arrests due to significant aggression, including incidents where officers were attacked with projectiles. Robinson addressed attendees, criticizing government policies and calling for a change of governance, while tech billionaire Elon Musk appeared via videolink. Counter-protesters emphasized unity against racism, with speeches from figures like independent MP Diane Abbott, who highlighted historical struggles against fascism. The police enforced strict divisions between the two groups and managed the events with over 1,000 officers deployed. The protests reflect ongoing tensions in UK society surrounding immigration and racial identity.
