British far-right activist Tommy Robinson, real name Stephen Yaxley-Lennon, was stopped and questioned by Metropolitan Police at London's Heathrow Airport on Saturday after flying back from Russia via Turkey. Officers invoked Schedule 3 of the Counter-Terrorism and Border Security Act 2019 — legislation targeting individuals suspected of involvement in hostile activity on behalf of a foreign state — seizing two of his phones for examination before releasing him after roughly three hours. The detention is significant because Russia is considered a hostile state by the UK and its Western allies, and Robinson had made remarks during his Moscow trip praising Russian society and dismissing the idea that Russia poses a threat to Britain, raising concerns among security analysts about potential foreign influence operations targeting UK domestic politics.
