Covering the area of Canvey Island, it is normally a strong Conservative seat, although it fell to Labour once, in the 1997 landslide. Bob Spink re-won the seat in 2001, but subsequently defected to the United Kingdom Independence Party (UKIP) on 22 April 2008 (becoming the first and so far only seat that UKIP has held in the House of Commons).
Following their review of parliamentary representation in Essex, the Boundary Commission for England has created a Castle Point constituency based entirely within the boundaries of the district council of the same name
