See 2023 Periodic Review of Westminster constituencies for further details.

The Boundary Commission for England formally launched the 2023 Review on 5 January 2021. 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 Devon be combined 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 would disappear, 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 would be renamed Torridge and Tavistock, and South Devon respectively.

The following seats are proposed:
