Douglas Carswell

Carswell co-founded Disruptive, a data analytics company. Companies House filings show that Carswell resigned as a Director on 10 April 2019.

Carswell was portrayed by actor Simon Paisley Day in the 2019 HBO- and Channel 4-produced drama Brexit: The Uncivil War.

As a member of the Conservative Party, Carswell was elected as the MP for Harwich in 2005, and for Clacton in 2010. In August 2014, he changed his political allegiance to UKIP and announced his resignation as an MP. He stood in the subsequent by-election and was returned as a UKIP MP. He explained that he was joining UKIP out of a desire to see "fundamental change in British politics" and because he believed "many of those at the top of the Conservative Party are simply not on our side. They aren't serious about the change that Britain so desperately needs." In 2016, Carswell admitted that he had "jumped ship with the express goal of changing the image of UKIP and ensuring that it was an asset rather than a liability in the referendum campaign…to decontaminate the brand". He left UKIP on 25 March 2017, to sit as an independent MP. He did not stand at the 2017 general election.

In March 2017, Carswell quit UKIP to become an independent MP for Clacton, leaving UKIP with no MPs in Parliament. On quitting the party he said, "Now we can be certain that that [Brexit] is going to happen, I have decided that I will be leaving Ukip."

On 20 April 2017, following the announcement two days earlier by Prime Minister Theresa May of a snap UK general election, Carswell confirmed he would not be a candidate in the June election.

His relationship with then-UKIP party leader Nigel Farage was full of "animosity" and "tension"; on several occasions he called for Farage to step down as party leader. Farage called Carswell "irrelevant" in response to them supporting different campaigns to leave the European Union in the 2016 referendum. In response to Carswell calling for the party leader's resignation, Farage said that Carswell should "put up or shut up", further saying that "either he's going to have to accept that [UKIP is unified] or do something different". After Farage's resignation as UKIP leader following the EU referendum, Carswell tweeted a "sunshades smiley emoji", which some parts of the media described as showing the "uneasy relationship" between the two men, Carswell later said to the BBC that "I tweet smiley faces all the time, I'm very optimistic". He also said that while Farage had "played a role" in the referendum, the resignation was "a huge opportunity" for the party. This happened a week after Farage suggested that Carswell could be kicked out of the party, saying that "We find somebody inside our party who doesn't agree with anything the party stands for, it's a very odd state of affairs".

Carswell also strongly advocated for electoral reform, including the right for constituents to be able to recall MPs. The Recall of MPs Act 2015 later became law.

At the 2015 United Kingdom general election, Carswell won the seat of Clacton with a majority of 3,437 – down from a majority of 12,404 in the 2014 by-election. Carswell won UKIP's only seat in the general election.

On 28 August 2014, Carswell defected from the Conservatives to UKIP. Although not required to do so, he resigned his seat as an MP, thus triggering a by-election. Less than a month before switching parties, Carswell had approved a letter from Conservative supporter Giles Watling to a local newspaper describing UKIP as a "one policy party" and saying "a vote for Ukip will be a vote for Labour". He later said he had been "decidedly cool towards the sentiments of the letter."

Following Carswell's resignation, Roger Lord, UKIP's nominated candidate for the 2015 general election, declared that he still wanted to stand, although the UKIP National Executive Committee voted to select Carswell. Two early opinion polls showed Carswell with a substantial lead. He was successful at the by-election on 9 October 2014, with a substantial majority of 12,404 votes over his nearest rival.

Carswell is a Eurosceptic, and supported Vote Leave – advocating leaving the EU – during the EU referendum in June 2016.

Even before the formation of the Coalition, the influence of Carswell's ideas was evident in speeches made by David Cameron – most notably a speech to the Open University made by David Cameron in Milton Keynes in May 2009.

In the new constituency of Clacton that was created from Harwich at the 2010 general election, Carswell increased his majority over Henderson to 12,068 votes. UKIP decided not to field a candidate against Carswell in the 2010 general election. Instead, the party actively campaigned in support of his re-election in view of his staunch anti-EU views.

In December 2009, Carswell tabled a Bill in the House of Commons calling for a public referendum on Britain's membership of the European Union (EU). The Daily Telegraph nominated him a Briton of the Year 2009, and Spectator readers voted him their choice as Parliamentarian of the Year in the same year. In February 2010, he asked Gus O'Donnell to suspend Cabinet meetings held outside London, when it was found that the government was using them to host Labour Party events in marginal seats.

In April 2008, Carswell was reported to be launching plans for Speaker Michael Martin to be removed after the 2010 general election, saying that the Speaker had "demonstrated that he is not the man to oversee the vital job of restoring faith in Westminster politics". Martin later became the first Speaker in 314 years to resign after cross-party criticism of his handling of the MPs' expenses scandal.

Carswell was elected to the House of Commons at the 2005 general election for the constituency of Harwich, defeating Ivan Henderson, the sitting Labour Member of Parliament (MP), by 920 votes. Carswell made his maiden speech on 28 June 2005 in the debate on the Identity Cards Bill. He was a member of Conservative Friends of Israel. Carswell served on the House of Commons' Education Select Committee and the Public Accounts Committee. In 2008, Carswell took part in an Armed Forces Parliamentary Scheme trip to Afghanistan, after which he called for more resources to be allocated to British troops serving there.

After being elected in 2005, Carswell originally designated a £1 million flat in London as his second home, and claimed over £21,000 for food, rent and furniture. In 2007 he began renting a house in Thorpe-le-Soken in Essex, which he designated his second home, and again paid a deposit and for furniture, including a £655 love seat, from his expenses (see Flipping § Second home flipping). Between 2007 and 2009 he claimed £32,000 in expenses for the house, commenting "I believe this is entirely justified". Following an investigation of the expenses of all MPs, Carswell was ordered to repay £2,159 in expenses.

At the 2001 general election, Carswell contested Sedgefield, the constituency of Prime Minister Tony Blair, as the Conservative candidate. Blair's majority fell by 7,430 votes with Carswell effecting a swing of 4.7% to the Conservatives compared to 1997, against a national swing of 1.8%. In the months before the 2005 general election, Carswell worked in the Conservative Party's Policy Unit, then run by David Cameron.

Carswell worked as corporate development manager for television broadcasting in Italy from 1997 until 1999, and later for Invesco.

The young Carswell was educated at two independent boarding schools for boys: St Andrews School in Turi in Kenya in East Africa, and Charterhouse in Godalming, Surrey, in southern England, followed by the University of East Anglia (UEA), where he was taught by Edward Acton, and graduated with an upper second-class honours bachelor's degree in history in 1993. He then attended King's College London, receiving a master's degree in British imperial history.

Carswell is the son of two physicians. He lived in Uganda until his late teens. His father, Wilson Carswell, a respected Scottish doctor and Fellow of the Royal College of Surgeons, diagnosed the first confirmed Ugandan cases of HIV/AIDS in the early 1980s, and was one of a number of people engaged in drawing the world's attention to the unfolding pandemic. His father's experiences in Uganda were the inspiration for the character Dr Nicholas Garrigan in Giles Foden's novel The Last King of Scotland. Carswell later attributed his libertarianism to his experiences of the "arbitrary rule" of Idi Amin.

John Douglas Wilson Carswell (born 3 May 1971) is a British former Member of Parliament who in 2014 became the first elected MP for the UK Independence Party (UKIP), representing Clacton. From March 2017 to May 2017 (general election), he sat as an independent.
