Polls close in Richmond Park by-election

Polls have closed in the Richmond Park by-election, triggered after Zac Goldsmith resigned as a Conservative MP in protest at the Heathrow expansion go-ahead. Neither the Tories nor UKIP is fielding candidates to stand against Mr Goldsmith, who secured a 23,000 majority from the 2015 general election. Both Mr Goldsmith and Ms Olney are against a third runway at the west London airport.
