Basildon was a parliamentary constituency represented in the House of Commons of the Parliament of the United Kingdom. It elected one Member of Parliament (MP) by the first past the post system of election. History The seat was created for the February 1974 general election from the majority of the abolished constituency of Billericay. Its electorate was reduced for the 1983 general election when Billericay was re-established. It underwent a major redistributions for the 1997 election and again for the 2010 election, when it was renamed as South Basildon and East Thurrock. It was one of the best known bellwether constituencies in Britain, having voted for the winning party in each election for the duration of its existence.
