Swales took Redcar from Labour incumbent Vera Baird for the Liberal Democrats in the 2010 general election, with a 21.8% swing.  Swales added over 10,000 votes to his 2005 general election total.  This was the biggest swing against any Labour candidate in the election and also the biggest gain by any Liberal Democrat.  He stood down at the 2015 general election. Lembit Öpik ( , ] ; born 2 March 1965) is a British politician.  A member of the Liberal Democrats, he served as a member of parliament (MP) representing the constituency of Montgomeryshire in Wales from 1997 until he lost his seat at the 2010 general election.

Robert Elwyn James Watkins, born in Rochdale, is a British Liberal Democrat politician.  He narrowly lost to Labour Party candidate Phil Woolas for the Oldham East and Saddleworth seat in the 2010 general election, but the result was overturned by an election court, which found that Woolas had knowingly lied about Watkins' personal character.  Watkins had stood down as a councillor representing Healey Ward on Rochdale Council in order to contest the general election.  He was selected as the Liberal Democrat candidate for the constituency in late 2007. Katie Green (born 28 August 1987) is an English model from Chichester, West Sussex.  She was first given an opportunity to model when a Surrey photographer arranged a test-shoot for her at Image Park Studio in West Sussex.  Green was originally signed to represent Wonderbra in July 2008, but her agency required her to lose weight, and she refused, ending her contract.  Green is unusual among models because of her height and weight and her refusal to lose weight to conform to the norms agencies expect of models.  She initiated a campaign against size zero models with Liberal Democrat MP Lembit Öpik.  Green continues to model and has appeared in numerous publications and campaigns. David Digby Rendel (15 April 1949 – 16 May 2016) was a British politician for the Liberal Democrats.  He was the Member of Parliament (MP) for Newbury from 1993 to 2005.

At the time he lost his seat he was the Liberal Democrats' spokesman on Higher and Further Education.  In September 2014, Rendel was selected as Liberal Democrat candidate in the 2015 general election for the seat of Somerton and Frome in Somerset; however, he lost to the Conservative candidate, David Warburton. The Liberal Democrats are a political party in the United Kingdom.  Party members elect the Leader of the Liberal Democrats.  Liberal Democrat Members of Parliament also elect a Deputy Leader of the Liberal Democrat Parliamentary Party in the House of Commons, often colloquially referred to as 'the Deputy Leader'.  Under the federal constitution of the Liberal Democrats the leader is required to be a member of the House of Commons. Alexander Morrison "Alistair" Carmichael (born 15 July 1965) is a Liberal Democrat politician and the Member of Parliament (MP) for the Scottish seat of Orkney and Shetland since the 2001 general election.
