The English ceremonial county of West Yorkshire is divided into 24 parliamentary constituencies: 12 borough constituencies and 12 county constituencies, two of which are partly in North Yorkshire.
See 2023 review of Westminster constituencies for further details.
For the 2023 review of Westminster constituencies, which redrew the constituency map ahead of the 2024 United Kingdom general election, the Boundary Commission for England opted to combine West Yorkshire with North Yorkshire as a sub-region of the Yorkshire and the Humber Region, resulting in the creation of two new cross-county boundary constituencies: Selby which comprises the majority of the former North Yorkshire district of Selby and includes the City of Leeds ward of Kippax and Methley; and a new constituency named Wetherby and Easingwold which includes the City of Leeds wards of Harewood and Wetherby.
As a consequence, the following changes were also made: Elmet and Rothwell was abolished; Wakefield was reconfigured to include the towns of Rothwell and Outwood and is renamed Wakefield and Rothwell; Morley and Outwood became Leeds South West and Morley; a new constituency named Ossett and Denby Dale was created; and the town of Normanton was transferred from Normanton, Pontefract and Castleford to Hemsworth, resulting in the two new constituencies of Pontefract, Castleford and Knottingley, and Normanton and Hemsworth.
Elsewhere, Batley and Spen, and Dewsbury were realigned to form Dewsbury and Batley, and Spen Valley, and Leeds West and Pudsey were abolished, with parts of each forming Leeds West and Pudsey. Leeds Central effectively became Leeds South and a new constituency named Leeds Central and Headingley was created. Although its boundaries were unchanged, it was proposed that Keighley be renamed Keighley and Ilkley.
The following constituencies resulted from the boundary review:
Covering electoral wards within Bradford
Covering electoral wards within Calderdale
Covering electoral wards within Kirklees
Covering electoral wards within Leeds
Covering electoral wards within Wakefield
Under the fifth periodic review of Westminster constituencies, the Boundary Commission for England decided to reduce the number of seats in West Yorkshire from 23 to 22, leading to significant changes in the Cities of Leeds and Wakefield, with the abolition of Elmet, Morley and Rothwell, Normanton, and Pontefract and Castleford and the creation of Elmet and Rothwell, Morley and Outwood, and Normanton, Pontefract and Castleford. Bradford North was renamed Bradford East.
