LONDON (REUTERS) - Several hundred noisy protesters marched through central London on Friday (Dec 13) to protest against Britain's election result, chanting "Boris Johnson: Not My Prime Minister" and "Boris, Boris, Boris: Out, Out, Out".

The protesters, brandishing signs that read "Defy Tory (Conservative) Rule" and "Refugees Welcome", walked at speed from outside Johnson's Downing Street residence to Trafalgar Square and on to the theatre 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.
