2014 Clacton by-election

A by-election for the United Kingdom parliamentary constituency of Clacton was held on 9 October 2014. It was triggered by incumbent Conservative Party MP Douglas Carswell defecting to the UK Independence Party (UKIP) and subsequently resigning his seat to seek re-election as its candidate. Carswell retained the seat with 59.7% of the vote, becoming UKIP's first elected MP. The Conservatives came second, and Labour third. UKIP's result was the biggest increase in the share of the vote for any party in any by-election in history, according to John Curtice, professor of politics at Strathclyde University. A by-election in Heywood and Middleton was held on the same day.
