# Selby (UK Parliament constituency)

Selby is a parliamentary constituency in North Yorkshire, represented in the House of Commons of the Parliament of the United Kingdom. It elects one Member of Parliament (MP) by the first past the post system of election. The constituency existed from 1983 to 2010 prior to reformation in 2024. It is currently held by Keir Mather of the Labour Party, who was first elected as an MP for the predecessor seat of Selby and Ainsty at a by-election in July 2023.

## History

This was a safe Conservative seat from 1983 to 1997 then became a Labour marginal for the remainder of its first existence. It was a notional gain for Labour at the 2024 general election, on a swing of over 24%.

## Boundaries
### 1983–2010

1983–1997: The District of Selby, and the District of Ryedale ward of Osbaldwick and Heworth.
The constituency covered the district of Selby and the south-eastern suburbs of the city of York (namely the parishes of Fulford, Heslington and Osbaldwick and Heworth Without). It included the University of York and the Drax and Eggborough power stations.
1997–2010: The District of Selby.

### 2007 Boundary Review

Following its review of parliamentary representation in York and North Yorkshire in the 2000s, the Boundary Commission for England created the new seat of Selby and Ainsty. This consisted of much of the former Selby constituency, minus the south-western suburbs of York which were included in the (also newly created) seat of York Outer, plus rural areas south and east of Harrogate formerly part of the abolished Vale of York constituency.

### 2023 Boundary Review

The 2023 periodic review of Westminster constituencies, which came into effect for the 2024 general election, recommended re-establishment of the constituency primarily from the abolished Selby and Ainsty constituency in North Yorkshire - excluding the Ainsty area and the North Yorkshire Council wards of Appleton Roebuck & Church Fenton and Tadcaster, and with the addition of the City of Leeds ward of Kippax and Methley in West Yorkshire.

### Since 2024

Under the 2023 periodic review of Westminster constituencies, the seat was defined as being composed of the following as they existed on 1 December 2020:
* The City of Leeds ward of: Kippax & Methley;
* The District of Selby wards of: Barlby Village; Brayton; Byram & Brotherton; Camblesforth & Carlton; Cawood & Wistow; Derwent; Eggborough; Escrick; Hambleton; Monk Fryston; Riccall; Selby East; Selby West; Sherburn in Elmet; South Milford; Thorpe Willoughby; and Whitley.
However, before the new boundaries came into effect, the District of Selby was abolished and absorbed into the new unitary authority of North Yorkshire with effect from 1 April 2023. Consequently, the constituency now comprises the following from the 2024 general election:
* The City of Leeds ward of Kippax & Methley.
* The North Yorkshire electoral divisions of: Barlby & Riccall; Brayton & Barlow; Camblesforth & Carlton; Cawood & Escrick; Cliffe & North Duffield; Monk Fryston & South Milford; Osgoldcross; Selby East; Selby West; Sherburn in Elmet; Thorpe Willoughby & Hambleton.
