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 and published their initial proposals on 8 June 2021.[3]

The commission has proposed retaining the current number of constituencies in Northamptonshire, as detailed below, with boundary changes to reflect changes to ward boundaries following the reorganisation of local government authorities within the county and to bring the electorates within the statutory range. It is proposed that Corby is renamed Corby and East Northamptonshire, and Wellingborough is renamed Wellingborough and Raunds.[4][5]
