Following their review of parliamentary representation in West Yorkshire, the Boundary Commission for England has recommended the creation of a new seat of Normanton, Pontefract and Castleford, taking the Normanton, Castleford and Pontefract towns from the district of Wakefield. Due to population decline, the Commission had to reduce the constituencies of the county by one, resulting in the "merger" of Normanton and Pontefract/Castleford seats.
The electoral wards used in the formation of this constituency, which was first fought at the 2010 general election are:
Airedale and Ferry Fryston, Altofts and Whitwood, Castleford Central and Glasshoughton, Knottingley, Normanton, Pontefract North, and Pontefract South
The Commission had great difficulty in naming the constituency, with "Normanton and Pontefract" and "Pontefract and Castleford" both suggested. On May 24, 2006 the modified name was chosen following further public consultation.
