Boundary changes

edit

2024

edit

For the 2023 Periodic Review of Westminster constituencies, which redrew the constituency map ahead of the 2024 United Kingdom general election, the Boundary Commission for England proposed that the number of seats in the combined area of Buckinghamshire and Milton Keynes be increased from seven to eight with the creation of a new cross-authority constituency named Buckingham and Bletchley. This led to significant changes elsewhere, with Milton Keynes Central replacing Milton Keynes South and Mid Buckinghamshire replacing the existing Buckingham seat.[3][4] These changes came into effect for the 2024 general election.

2010

edit

Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England[5] decided to retain Buckinghamshire's 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. The changes included the return of Great Missenden to Chesham and Amersham, Hazlemere to Wycombe and Aston Clinton to Buckingham. In addition, Marlow was transferred from Wycombe to Beaconsfield and Princes Risborough from Aylesbury to Buckingham. The boundary between the two Milton Keynes constituencies was realigned and they were renamed as Milton Keynes North and Milton Keynes South.
