History
This constituency was created in 1950 when the two-member constituency of Brighton was split into three single-member seats.
 * History of boundaries

Boundary changes for the 1997 general election moved Peacehaven, a semi-rural area, into the constituency. This added a ward where the Conservatives had been favoured, but Labour gained the seat at its landslide victory. Des Turner held it until 2010, when Simon Kirby of the Conservative Party won it.
 * History of results

For a total of 48 years since the seat's creation, it has been Conservative-controlled (1950–1964; 1970–1997; 2010–2017). The only other party to hold the seat since its creation has been the Labour Party.

Labour first won Kemptown in 1964, with a narrow majority of just seven votes. Dennis Hobden, the first Labour MP to ever be elected in Sussex, increased his majority in 1966, but lost the seat in 1970, and another Labour MP was not returned until 1997. The seat was a national bellwether constituency from 1979 to 2015, but in 2017 elected a Labour MP when the country as a whole returned a hung parliament with the Conservatives being the largest party by a margin of 56 MPs.

Liberal Democrats and their two predecessor parties following national trends formed the third-largest party in the constituency, 1950–2010 inclusive. The 2010 general election result for the party can be seen as 0.6% behind "its" highest, at 18.6%, if including its SDP forerunner. The Liberal Democrat vote share collapsed to 3% in 2015 (behind UKIP and Green Party candidates) and remained at the 3% level in 2017 despite the absence of UKIP and Green candidates for the seat at that election.

The Green Party candidate finished in fourth place at the 2005, 2010 and 2015 elections, retaining their deposit each time, with vote shares ranging from 5.5% to 7.0%. The Greens did not field a candidate in 2017 and endorsed Labour, who subsequently gained the seat with a majority of just under 10,000 votes.

The 2015 general election result had made the seat the tenth-most marginal majority of the Conservative Party's 331 seats by percentage of majority.

On 29 May 2024, Russell-Moyle announced that he had received a letter that he had been suspended from membership of the Labour Party, because of what he believed was a vexatious complaint, which made him ineligible to be their candidate at the 2024 United Kingdom general election.
