The seat was won in 2024 by Josh Babarinde, a Liberal Democrat MP, beating Conservative MP Caroline Ansell. Ansell held the seat from 2015 to 2017 and again from 2019 to 2024, in both cases beating the Liberal Democrat MP Stephen Lloyd, who held it from 2010 to 2015 and again from 2017 to 2019.[n 2] Since the seat's creation it has been won by candidates from either of these two political parties (and their early forebears, the Liberal Party and the Unionist Party). The seat has had four by-elections, most recently in 1990.
For 94 years of the 20th Century, the seat was represented by Conservative MPs. The seat in the 1930s saw three unopposed candidates: in 1932, March 1935 and November 1935. More recently, Eastbourne has been considered relative to others a very marginal seat, or swing seat. In the nine elections from 1990 to 2019, the winning majority was never more than 10%, and the seat changed hands between the Conservative and Liberal Democrat candidates in seven of the last ten elections.
Chris Hanretty, the Professor of Politics at Royal Holloway, estimated that Eastbourne voted 57.6% to 42.4% in favour of leaving the European Union during the 2016 referendum.[3]

Reduced to bring its electorate within the permitted range by transferring the parts within District of Wealden to the Lewes constituency.[2]
From 1910 until 1987 the seat returned Conservative Party candidates at every election. The large rural vote within the seat, until boundary changes in 1983, resulted in strong Conservative support – rural English voters tended to be richer and more right-wing (anti-socialist, pro-Empire before 1960s, pro-Established Church and pro-defence) compared to other voters.
The seat became a marginal, or swing seat, from the 1990 by-election onwards, being closely fought for between the two locally dominant parties. A Liberal Democrat gained the seat at the 2010 general election, in a vote which saw Eastbourne return the sixth-lowest Labour share of the vote of the 631 candidates who stood at the election, with only 4.8%.[4] In 2015, the seat was the 9th most marginal of the Conservative Party's 331 seats, by share of the vote.[5]
This constituency underwent boundary changes between the 1992 and 1997 general elections and thus change in share of vote is based on a notional calculation.
Another General Election was required to take place before the end of 1915. The political parties had been making preparations for an election to take place and by July 1914, the following candidates had been selected;
