See2023 review of Westminster constituencies for further details.
For the2023 review of Westminster constituencies, which redrew the constituency map ahead of the2024 United Kingdom general election, theBoundary 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 constituency ofEast Hampshire were transferred into a new cross-county (and ‘majority-Surrey’) constituency with Surrey namedFarnham and Bordon.
In addition,Fareham andMeon Valley were abolished and replaced by the constituencies ofFareham and Waterlooville, andHamble Valley.[1][2]
The boroughs and districts and unitary authorities constituting the ceremonial county of Hampshire contributed to the new set of Hampshire constituencies as follows:
Containing electoral wards fromBasingstoke and Deane
Containing electoral wards fromEast Hampshire
Containing electoral wards fromEastleigh
Containing electoral wards fromFareham
Containing electoral wards fromGosport
Containing electoral wards fromHart
Containing electoral wards fromHavant
Containing electoral wards fromNew Forest
Containing electoral wards fromPortsmouth
Containing electoral wards fromRushmoor
Containing electoral wards fromSouthampton
Containing electoral wards fromTest Valley
Containing electoral wards fromWinchester
Under thefifth periodic review of Westminster constituencies, theBoundary Commission for England decided to increase the number of seats which covered Hampshire from 17 to 18, with the creation ofMeon Valley. As a consequence of resulting boundary changes,Romsey was renamedRomsey and Southampton North. The Aldershot and Basingstoke seats, more predominantly urban than previously defined, were redesignated as borough constituencies.
