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. 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 recommendations were published on 28 June 2023.

The commission proposed retaining the eight current constituencies in Dorset, with minor boundary changes to reflect changes to ward boundaries following the reorganisation of local government authorities within the county.
