UKIP have announced that they won't field a candidate in the election for Richmond Park.
Zac Goldsmith resigned as the Conservative MP for Richmond Park, after the Government backed plans to build a third runway at Heathrow. This meant a by-election has been triggered, in which he will stand as an independent.
A spokeperson for UKIP said: "Zac Goldsmith has resigned on a matter of principle and UKIP admire him for having the courage to do so. UKIP have always believed that Gatwick was a preferred option to Heathrow.
"Recognising Zac as a principled man, who was fully committed to helping get Britain out of the European Union, UKIP leader Nigel Farage, in conjunction with our National Executive Committee have agreed that we will not be fielding a candidate in the upcoming by-election for Richmond Park.
"The Liberal Democrats are committed to overturning the result of the 2016 referendum and ignoring the will of the British people. This must not be allowed to happen.
"UKIP are encouraging all of our supporters and voters to support Zac Goldsmith in his bid to become an independent MP."
