2010 boundary changes

Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England decided to increase the number of seats which covered Hampshire from 17 to 18, with the creation of Meon Valley. As a consequence of resulting boundary changes, Romsey was renamed Romsey and Southampton North. The Aldershot and Basingstoke seats, more predominantly urban than previously defined, were redesignated as borough constituencies.

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.^[3] Initial proposals were published on 8 June 2021 and, following two periods of public consultation, revised proposals were published on 8 November 2022. The final proposals were published on 28 June 2023.

The commission has proposed that Hampshire be combined with Berkshire and Surrey as a sub-region of the South East Region. As a result, parts of the current constituency of East Hampshire would be included in a new cross-county boundary constituency named Farnham and Bordon. In addition, Fareham and Meon Valley would be abolished and replaced by Fareham and Waterlooville, and Hamble Valley.^[4][5]
