Boundary changes

2024

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 Lincolnshire with Leicestershire and Rutland in a sub-region of the East Midlands region, creating one additional seat by re-establishing the constituency of Rutland and Stamford, spanning all three counties. Consequently, Stamford was removed from the constituency of Grantham and Stamford, which was renamed Grantham and Bourne.
