The ceremonial county of Berkshire (which is entirely made up of unitary authorities – Bracknell Forest, Reading, Slough, West Berkshire, Windsor and Maidenhead and Wokingham) is divided into eight parliamentary constituencies: two borough constituencies and six county constituencies. Constituencies 2010 boundary review Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England decided to retain Berkshire's 8 constituencies for the 2010 election, making minor changes to realign constituency boundaries with the boundaries of current local government wards, and to reduce the electoral disparity between constituencies, including the transfer of Bray from Windsor to Maidenhead, Binfield from Bracknell to Windsor and the return of Foxborough ward from Windsor to Slough. Proposed boundary changes See 2023 Periodic Review of Westminster constituencies for further details. Following the abandonment of the Sixth Periodic Review (the 2018 review), the Boundary Commission for England formally launched the 2023 Review on 5 January 2021. Initial proposals were published on 8 June 2021 and, following two periods of public consultation, revised proposals were published on 8 November 2022. Final proposals will be published by 1 July 2023. The commission has proposed that Berkshire be combined with Hampshire and Surrey as a sub-region of the South East Region. As a result, Windsor now includes Englefield Green in the Surrey borough of Runnymede.
