# Reading West and Mid Berkshire (UK Parliament constituency)

Reading West and Mid Berkshire is a constituency in the House of Commons of the UK Parliament. It was formed as a result of the 2023 Periodic Review of Westminster constituencies and primarily replaced the former Reading West constituency, also subsuming parts for the Newbury and Wokingham constituencies. It was first contested at the 2024 general election. Since 2024 it has been represented by Olivia Bailey of the Labour Party.
Some 30% of the constituency's voters live in the Borough of Reading, with the remainder living in the West Berkshire local government area.

## History

At the time of the 2023 Periodic Review of Westminster constituencies, there were eight constituencies in the county of Berkshire. Of these constituencies, only three (Reading East, Reading West, and Windsor) were within the permitted electorate range of no fewer than 69,724 electors and no more than 77,062. All of the remaining constituencies were above the upper limit. The Boundary Commission for England therefore proposed the addition of a ninth constituency within the county.
Whilst both Reading constituencies could have remained unchanged, the boundary commission instead proposed a reconfiguration to account for the increased electorates of the surrounding constituencies, and to better reflect local ties in the surrounding communities. This involved the creation of two new constituencies (Earley and Woodley and Mid Berkshire), both with the bulk of their electorate outside the Borough of Reading but including outer wards of the borough, together with a new Reading Central constituency entirely within the borough.
During the process of acceptance of these proposals, the name was changed from Mid Berkshire to West Reading and Mid Berkshire, despite the relative small proportion of the constituency that is within Reading. The new constituency includes three borough wards and twelve wards from West Berkshire, as opposed to seven and six respectively for the old Reading West constituency.

## Constituency profile

The constituency has a mixed nature, including parts of the continuously built-up urban area of Reading (both within and without the boundaries of the borough) and an extensive rural area, which includes villages such as Aldermaston, Aldworth, Bradfield, Basildon, Bucklebury, Burghfield, Compton, East Ilsley, Hampstead Norreys, Mortimer, Pangbourne, Streatley, Theale, West Ilsley, Woolhampton and Yattendon. Some 30% of the constituency's voters live in the Borough of Reading, with the remainder living in the West Berkshire local government area.
The wards that make up the constituency are represented by 26 councillors. As of November 2023, these comprise 11 Liberal Democrats, 8 Conservatives, 6 Labour and 1 Green.

## Boundaries

The constituency is composed of the following wards (as they existed on 1 December 2020):
* The Borough of Reading wards of: Kentwood, Norcot, and Tilehurst; and
* The District of West Berkshire wards of: Aldermaston, Basildon, Bradfield, Bucklebury, Burghfield & Mortimer, Downlands (polling district BC), Pangbourne, Ridgeway, Theale, Tilehurst & Purley, Tilehurst Birch Copse, and Tilehurst South & Holybrook.
The Reading wards, together with Pangbourne, Theale and the three Tilehurst wards in West Berkshire, comprising 67% of the electorate, were previously in the Reading West seat, with the remaining areas coming from Newbury and Wokingham in equal parts.
The seat is bordered by the parliamentary constituencies of Newbury, Didcot and Wantage, Henley and Thame, Reading Central, Earley and Woodley, Wokingham, North East Hampshire, and North West Hampshire.
