In the 2014 European elections, UKIP defied expectations to become the largest British party in the European Parliament.
Twenty four UKIP MEPs were elected and the party won 27.5% of the vote – an achievement its then leader Nigel Farage described as “historic”.
UKIP’s success in these elections was one of the factors behind David Cameron promising a referendum on Brexit – as he feared losing more Conservative voters to UKIP.
