Douglas was first elected to Parliament in 2005 by a slender 920 votes. He was returned as MP for Clacton in 2010 with a 12,000 majority.
In August 2014, frustrated by their failure to deliver political reform, Douglas left the Conservative party and joined UKIP. He became the first MP in a generation to chose to resign from the Commons, and face a by-election when changing parties. He did so because he felt he needed permission from his electorate.
In the subsequent Clacton by-election, Douglas won an increased majority, becoming UKIP's first elected MP. According to Professor John Curtice, an elections expert, Douglas' win was "the largest increase in the vote achieved by any party" in any by-election in British political history.
Douglas is passionate about change. His book, The End of Politics and the Birth of iDemocracy, has been described as a "revolutionary text ... right up there with the Communist manifesto" by Dominic Lawson, writing in the Sunday Times.
In recognition of his efforts to bring change to Westminster, in 2009 Spectator readers voted him Parliamentarian of the Year and The Daily Telegraph nominated him a Briton of the Year.
Douglas had a proper job in business before politics, working in commercial television and then fund management.
Born in 1971, Douglas' home was in Uganda until his late teens. He read history at the University of East Anglia and King's College, London.
Douglas first stood for Parliament against Tony Blair, as the Conservative candidate for Sedgefield in 2001. Married to Clementine, with a daughter, Douglas is keen on swimming, running and riding. He is an enthusiastic - if not always successful - gardener.
In 2008, he co-authored the best selling book, The Plan, with Daniel Hannan MEP. According to commentator Charles Moore, Downing Street has since "enthusiastically lifted several bits of it". Douglas wishes they would implement even more.
Douglas has written for the Financial Times, Sunday Times, Daily Telegraph, Mail on Sunday and Spectator, and appears regularly on television and radio.
