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 Lancashire with Cumbria as a sub-region of the North West Region, with the existing seat of Morecambe and Lunesdale extending into southern Cumbria to create a cross-county boundary constituency. Wyre and Preston North was abolished, with its contents being distributed to five neighbouring constituencies. As a consequence, Lancaster and Fleetwood, and Blackpool North and Cleveleys reverted back to the previous names of Lancaster and Wyre, and Blackpool North and Fleetwood respectively. Other proposed changes included the expansion of Pendle to become Pendle and Clitheroe.^[3] Four wards in the borough of West Lancashire were incorporated into the Merseyside constituency of Southport.^[4][5]

The following constituencies were proposed:

Containing electoral wards from Blackburn with Darwen

• Blackburn
• Rossendale and Darwen (part)

Containing electoral wards from Blackpool

• Blackpool North and Fleetwood (part)
• Blackpool South

Containing electoral wards from Burnley

• Burnley (part)

Containing electoral wards from Chorley

• Ribble Valley (part)

Containing electoral wards from Ribble Valley

Containing electoral wards from West Lancashire

• Southport (part also in the Merseyside borough of Sefton)
• West Lancashire

Containing electoral wards from Wyre

• Blackpool North and Fleetwood (part)
• Fylde (part)
• Lancaster and Wyre (part)

Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England decided to increase Lancashire's representation from 15 to 16 constituencies, with the creation of Wyre and Preston North CC. Lancaster and Wyre was reconfigured and became Lancaster and Fleetwood, and Blackpool North and Fleetwood became Blackpool North and Cleveleys. Other changes were made to realign constituency boundaries with the boundaries of current local government wards, and to reduce the electoral disparity between constituencies.
