Ellie Chowns, Green Party MEP, is arrested after standing in solidarity with protesters in Trafalgar Square. Police have ordered climate change protesters to stop their action immediately or face arrest, in an effort to put an end to more than a week's disruption in London. Activists with Extinction Rebellion (XR) have been told to leave Trafalgar Square, where many have congregated lawfully since Monday last week, as police seek to expunge the protesters from the capital. More than 1,400 people have been arrested during eight days' XR action, with the threat that anyone defying police orders will also be detained.
