## 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.

### 2010

In the Fifth Review the Boundary Commission for England recommended that Lincolnshire retained its current constituencies, with minor changes only to reflect revisions to local authority ward boundaries and to reduce the electoral disparity between constituencies.
