The protest turned violent, as protesters pushed against lines of police. One protester was seen bleeding from his mouth after security forces clashed with demonstrators.
Brandishing signs that read “Defy Tory (Conservative) Rule” and “Refugees Welcome”, protesters marched at speed from outside Johnson’s Downing Street residence to Trafalgar Square and on to the theater district, blocking traffic and drawing a heavy police presence.
Johnson’s Conservatives won Thursday’s election by a large margin. On Friday he called for “closure” over the Brexit divisions that have riven the United Kingdom for the past three and a half years.
