Edinburgh South (UK Parliament constituency)

Edinburgh South is a constituency of the House of Commons of the UK Parliament created in 1885. The constituency has been held by Scottish Labour since 1987. The seat has been represented since 2010 by Ian Murray, who formerly served as Secretary of State for Scotland in the government of Keir Starmer between July 2024 and September 2025.

Prior to the 2005 general election, the constituency had the same boundaries as the Edinburgh South Scottish Parliament constituency, now replaced by the Edinburgh Southern Scottish Parliament constituency.

History

;Summary of results
A candidate fielded by the Labour Party has won the seat since 1987. Prior to that the political division for Westminster purposes voted for the Conservative and Unionist candidate, ahead of all other candidates by single preference, at each Westminster election from and including 1918. Back then, the electorates' single-most preferred candidate in simple voting was that of the Liberal Party, except in 1900 when a Liberal Unionist was returned. The 2015 result gave the seat the 23rd-smallest majority of Labour's 232 seats by percentage of majority. In the 2017 general election, Ian Murray received the highest voteshare of any Scottish candidate and was also one of only two constituencies in Scotland where the winning candidate received a majority of the votes cast.
Edinburgh South is one of three constituencies in Scotland to have never elected an MP from the Scottish National Party at any point in history, alongside Dumfriesshire, Clydesdale and Tweeddale; and Orkney and Shetland.
;Recent opposition candidates' performance
At the 2015 general election three of the seven parties' candidates standing retained their deposits, their votes exceeding 5%. Those doing so and not winning were SNP – 33.8% of the vote, and Conservative – 17.5% of the vote. At this election, the SNP increased their share of the vote by over 26%, coming a close second to Murray.
The Liberal Democrat candidate of 2005 fell within 0.9% of a winning majority. The Liberal Democrats' swing nationally was −15.2% swing in 2015. The swing in this seat against the party was however −30.3% resulting in the loss of their deposit, a fate not sustained by either of the party's two formative parties in the seat since 1970.
;Turnout
Turnout has ranged between 81.1% in 1950 and 57.7% in 2001.
;2016 EU referendum
