Theceremonial county ofMerseyside, created in 1974, is divided into 16parliamentary constituencies (sub-classified into 11 ofborough type and five ofcounty status affecting the level of expenses permitted and status of returning officer). Three seats cross the county boundary - two are shared with Cheshire and one with Lancashire.
The area, centred on its largest city ofLiverpool, has since that year elected a majority ofLabour Party MPs moreover since 1997 at least 13 of 15 seats have been held or won by the party at each general election, with the party winning all seats for the first time in 2024. The two other largest parties nationally in England (Conservatives andLiberal Democrats) have to date won intermittently in the two larger seats within the four inthe Wirral, the peninsula facing Liverpool, and, until 2024, had alternately represented the seat centred on the coastal strip in and around the leisure resort ofSouthport; it had not previously sided with the Labour Party since it was created in 1885. The bulk of seats especially towards the east and the centre ofLiverpool have not sided with theConservative Party since that party actively supported theNational Labour Organisation (1931–1947).

See2023 Periodic Review of Westminster constituencies for further details.
For the2023 Periodic Review of Westminster constituencies, which redrew the constituency map ahead of the2024 United Kingdom general election, theBoundary Commission for England opted to combine Merseyside with Cheshire as a sub-region of the North West Region, with the creation of two cross-county boundary constituencies ofEllesmere Port and Bromborough, andWidnes and Halewood, which avoids the need for a constituency which spans the River Mersey. As a consequence,Garston and Halewood was abolished andLiverpool Garston re-established, andWirral South was abolished, with its contents being redistributed toBirkenhead, Ellesmere Port and Bromborough, andWirral West. Four wards in the Lancashire borough of West Lancashire were included inSouthport.[1][2]

Under theFifth Periodic Review of Westminster constituencies, theBoundary 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 singleKnowsley constituency created. Parts ofKnowsley North and Sefton East were added to the new constituency ofSefton Central, which replacedCrosby, and parts ofKnowsley South were added to the new constituency ofGarston and Halewood, which replacedLiverpool, Garston.
