Parliamentary career
In November 1999,Teresa Gorman announced intention to stand down at the next general election from Billericay. [13] Baron was selected to defend Billericay at the 2001 general election,when he was elected as MP for Billericay with 47.4% of the vote and a majority of 5,013. [14] He made his maiden speech on 20 July 2001. [15]
Baron was a member of Iain Duncan Smith's frontbench team,but resigned in March 2003 in protest at his support of the Iraq War. [16] He was re-appointed by Duncan Smith as a health spokesman four months later, [17] a position he held until July 2007 when he was moved to the Conservative Whip's Office.
At the 2005 general election,Baron was re-elected as MP for Billericay with an increased vote share of 52.2% and an increased majority of 11,206. [18]
Baron was a strong backer of David Davis in the 2005 Conservative leadership election,having also supported him in the 2001 leadership contest won by Iain Duncan Smith. [19]
Prior to the 2010 general election,Baron's constituency of Billericay was abolished,and was replaced by Basildon and Billericay. At the general election,Baron was elected as MP for Basildon and Billericay with 52.8% of the vote and a majority of 12,338. [20] [21]
Baron was the only Conservative among just 15 MPs [22] who voted against British participation in the attack on Libya in the Commons on 21 March 2011. In 2013 he tabled a backbench motion to mandate a vote in Parliament before providing "lethal support" to anti-government forces in Syria,which ultimately prevented further military intervention when the government was unable to secure the necessary parliamentary support [23] and he was also part of a minority voting against the government on air strikes against Islamic State of Iraq and the Levant. [24]
In June 2012,Baron delivered a letter,signed by over 100 Tory MPs,to the Prime Minister David Cameron urging him "to place on the Statute Book before the next General Election a commitment to hold a referendum during the next Parliament on the nature of our relationship with the European Union". [25] In May 2013 he tabled a rebel amendment to the Queen's Speech to "express regret" that a referendum on the EU could not be held sooner,which was backed by over 100 MPs. [26]
His reputation as a Eurosceptic and "serial rebel" [27] saw his name mentioned as a possible defector to the UK Independence Party. Speaking to the BBC's Newsnight in response to speculation in late 2014,Baron said:"You should never say never in politics,but the bottom line is my very strong preference is to stay within the Conservative party." [27]
In July 2014,Mark d'Arcy of the BBC named Baron his choice in "Parliamentarians of the Year" for 2013/14 for his role in opposing military action in Syria and seeking a promise of a referendum on membership of the European Union,writing that "he is not a household name or a fiery orator,but his fingerprints are all over the two most significant parliamentary events of the last 12 months." [23]
At the 2015 general election,Baron was re-elected as MP for Basildon and Billericay with a decreased vote share of 52.7% and an increased majority of 12,482. [28] [29]
