See 2023 Periodic Review of Westminster constituencies for further details.
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 Devon with Avon and Somerset as a sub-region of the South West Region, resulting in significant change to the existing pattern of constituencies. In Devon, East Devon, and Tiverton and Honiton were abolished, being replaced by Exmouth and Exeter East, Honiton and Sidmouth, and the cross-county boundary constituency of Tiverton and Minehead. Torridge and West Devon and Totnes were renamed Torridge and Tavistock, and South Devon respectively, despite only minor boundary changes to each.
The following seats resulted from the boundary review:
Containing electoral wards from East Devon
Containing electoral wards from Exeter
Containing electoral wards from Mid Devon
Containing electoral wards from North Devon
Containing electoral wards from Plymouth
Containing electoral wards from South Hams
Containing electoral wards from Teignbridge
Containing electoral wards from Torbay
Containing electoral wards from Torridge
Containing electoral wards from West Devon
