MPs, friends and campaigners gathered to remember former Cambridge professor after his death on Friday

Tens of thousands of people gathered in Trafalgar Square in London to remember and pay tribute to Jason Arday, the former Cambridge professor who died on Friday.

Stand Up to Racism, which organised the vigil, estimated that 30,000 mourners had gathered in the square to listen to emotional speeches from MPs, friends and campaigners on Arday’s life and legacy and join in a minute’s silence. Many were dressed in black and held flowers, which they were asked to leave beneath Nelson’s column. People also carried placards reading “rest in power”.
