Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England[3] 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.

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.[4] 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 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 constituency named Mid Buckinghamshire. This leads to significant changes elsewhere, particularly in Milton Keynes, with the creation of a cross-authority constituency named Buckingham and Bletchley, replacing the existing Buckingham seat.[5][6]

The following constituencies are proposed:

Containing electoral wards from Buckinghamshire (unitary authority)

• Aylesbury
• Beaconsfield
• Buckingham and Bletchley (part)
• Chesham and Amersham
• Mid Buckinghamshire
• Wycombe

Containing electoral wards from Milton Keynes

• Buckingham and Bletchley (part)
• Milton Keynes North
• Milton Keynes South
