The Sea wall is a term used by psephologists to refer to 108 constituencies along the UK coastline, generalising them as marginal.[1] They formed before the July 2024 election a majority of Conservative pluralities, so seats, many or most marginal enough to be vulnerable to Labour according to opinion polls.[2][3] As to the Red and Blue walls, the Sea wall overlaps both[4] and was used in some coverage of the 2024 general election.[5] From the 2019 general election to July 2024, Labour held 24 of these seats.[6]
These seats in England and Wales are noted, relative to the national average, for deprivation.[7][8] They are personified by tourism-based economies, the cost of living crisis, and poor connectivity.[9] Coastal residents bring home on average lower wages.[10] The availability of affordable housing has also been an issue.[11]
Before the 2024 general election, the think tank Onward called coastal areas “the forgotten battleground that could decide [this] election”.[12]
Research from the Fabian Society was reported on that Labour had unprecedented polling leads over the Conservatives.[15] The "sea wall" is regarded by them as an important area for the 2024 general election.[16]YouGov polling showed that 44% of voters in the Sea wall said they would never consider voting Conservative.[17]
