Hundreds of people have marched from New Scotland Yard to Parliament Square, defying lockdown rules, to protest against the police's handling of the Sarah Everard vigil in Clapham on Saturday. People are seen chanting and marching through central London before gathering outside the Commons. The Met commissioner, Dame Cressida Dick, has said she will not quit, despite the home secretary and mayor of London expressing dissatisfaction at her justification for policing at the vigil
