The Metropolitan Borough of Sefton wards of: Birkdale; Cambridge; Duke’s; Kew; Meols; Norwood.
The Borough of West Lancashire wards of: Hesketh-with-Becconsall; North Meols; Rufford; Tarleton.[2]
The four, largely rural, West Lancashire Borough wards were transferred from South Ribble, offset by the loss of Ainsdale ward to Sefton Central.
Following a local government boundary review in West Lancashire which came into effect in May 2023,[3][4] the constituency will now comprise the following from the 2024 general election:
The Metropolitan Borough of Sefton wards of: Birkdale; Cambridge; Duke’s; Kew; Meols; Norwood.
The Borough of West Lancashire wards of: Burscough Bridge & Rufford (part); North Meols & Hesketh Bank; Tarleton Village.[5]
Until 2024, the constituency had been a Liberal or Conservative seat throughout its history, and marginal for much of that time, meaning that it changed hands 11 times between the parties after it was created in 1885, having had nine Conservative MPs and eight Liberal or Liberal Democrat MPs in its history.
During the nadir of the Liberal Party, from the 1930s to the 1960s, the constituency became a safe Conservative seat, with absolute majorities from 1931 until 1970 inclusive.
With the revival the Liberal Party's fortunes in the early 1970s, elections became close contests once again. The constituency changed hands in the 1987 general election, when it was won by Ronnie Fearn of the Liberal Party, for the SDP-Liberal Alliance, shortly before the two parties merged to form the Liberal Democrats. Fearn had contested the seat unsuccessfully for the Liberals throughout the 1970s.
Fearn lost the seat to the Conservatives' Matthew Banks at the 1992 election, one of the few Conservative gains at that election, only to regain it at the 1997 election. The Liberal Democrats held the seat, under John Pugh (after Fearn stood down) in 2001 until 2017.
The seat was one of the eight Liberal Democrat seats that survived its national vote share collapse at the 2015 general election, although there was a higher-than-average drop in the Liberal Democrats' vote share. Pugh opted not to re-contest the seat in the 2017 general election, at which it returned to the Conservatives, the only seat the Tories gained from the Liberal Democrats in 2017 (aside from Richmond Park, which they had gained at a 2016 by-election).
In 2019, a resurgent Labour vote pushed the Liberal Democrats into third place for the first time since 1966 with the seat becoming a Tory-Labour marginal. Labour won the seat from the Conservatives in 2024, making it the first time Labour has held the seat, as well as the first time Labour has held every seat in Merseyside.
