Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England decided to reduce the number of seats in Merseyside from 16 to 15, leading to significant changes. The two Knowsley seats were abolished, with a single Knowsley constituency created. Parts of Knowsley North and Sefton East were added to the new constituency of Sefton Central, which replaced Crosby, and parts of Knowsley South were added to the new constituency of Garston and Halewood, which replaced Liverpool, Garston.

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.^[3] 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 proposals were published on 28 June 2023.

The commission has proposed that Merseyside be combined with Cheshire as a sub-region of the North West Region, with the creation of two cross-county boundary constituencies of Ellesmere Port and Bromborough, and Widnes and Halewood, which avoids the need for a constituency which spans the River Mersey. As a consequence, Garston and Halewood would be abolished and Liverpool Garston re-established, and Wirral South would be abolished, with its contents being redistributed to Birkenhead, Ellesmere Port and Bromborough, and Wirral West. Four wards in the Lancashire borough of West Lancashire would be included in Southport.^[4][5]

The following constituencies are proposed:

Containing electoral wards from Knowsley

• Knowsley
• Liverpool West Derby (part)
• St Helens South and Whiston (part)
• Widnes and Halewood (part also in Cheshire West and Chester)

Containing electoral wards from Liverpool

• Liverpool Garston
• Liverpool Riverside
• Liverpool Walton (part)
• Liverpool Wavertree
• Liverpool West Derby (part)

Containing electoral wards from St Helens

• St Helens North
• St Helens South and Whiston (part)

Containing electoral wards from Sefton

• Bootle
• Liverpool Walton (part)
• Sefton Central
• Southport (part also in West Lancashire)

Containing electoral wards from Wirral

• Birkenhead
• Ellesmere Port and Bromborough (part also in Cheshire West and Chester)
• Wallasey
• Wirral West
