The constituency includes the town of Braintree at its southern end, and a large area of rural Essex to the north, including the town of Halstead.
History
The seat was created for the February 1974 general election, largely from the majority of the constituency of Maldon, including the towns of Braintree and Witham. It underwent a major redistribution for the 2010 general election when Witham was formed as a separate constituency. This resulted in making the seat safer for the Conservatives.
The former Leader of the House Tony Newton held the seat for the Conservatives from its creation in 1974 until 1997 when Alan Hurst defeated Newton to gain the seat for Labour. Brooks Newmark defeated Hurst in 2005 to regain the seat for the Conservatives, and held it until he stood down in 2015, being succeeded by James Cleverly, also a Conservative.[3]
