The ceremonial county of Hampshire, which includes the unitary authorities of Portsmouth and Southampton, is divided into 19 parliamentary constituencies: 9 borough constituencies and 10 county constituencies. One of the county constituencies, Farnham and Bordon is split between Hampshire and Surrey
See also: 2024 United Kingdom general election.
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 opted to combine Hampshire with Berkshire and Surrey as a sub-region of the South East Region. As a result, parts of the current constituency of East Hampshire were transferred to a new cross-county boundary constituency with Surrey named Farnham and Bordon. In addition, Fareham and Meon Valley was abolished and replaced by the new constituencies of Fareham and Waterlooville, and Hamble Valley.[3] [4]
The following constituencies are proposed:
Containing electoral wards from Basingstoke and Deane
Containing electoral wards from East Hampshire
Containing electoral wards from Eastleigh
Containing electoral wards from Fareham
Containing electoral wards from Gosport
Containing electoral wards from Hart
Containing electoral wards from Havant
Containing electoral wards from New Forest
Containing electoral wards from Portsmouth
Containing electoral wards from Rushmoor
Containing electoral wards from Southampton
Containing electoral wards from Test Valley
Containing electoral wards from Winchester
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.
