Boris Johnson boasted he voted in local elections yesterday despite polls in his London constituency not taking place.
The former foreign secretary tweeted his support for the Conservatives and encouraged his 550,000 followers to do the same.

The message was left on his profile for just under a minute after other social media users pointed out no polls were taking place in London.
