Scottish Labour experienced one of their worst defeats ever, at the 2015 general election. Scottish Labour were left with a sole seat in the House of Commons, Edinburgh South, and lost 40 of its 41 seats to the SNP. This was the first time the party had not dominated in Scotland since the Conservative Party landslide in 1959. At the 2016 Scottish Parliament election, the party lost 13 of its 37 seats, becoming the third-largest party after being surpassed by the Scottish Conservatives. At the 2017 general election, Scottish Labour improved their fortunes and gained six seats from the SNP, bringing its total seat tally to seven and winning a 27% share of the vote. This was the first time since the 1918 general election, 99 years previously, that Labour had finished in third place at any general election in Scotland. Overall, the 2017 general election marked the first time in twenty years that the Labour Party had made net gains in the UK at any election. The success was short-lived however, and at the 2019 general election, Labour lost all new seats gained two years earlier, and again were left with Edinburgh South as their only seat in Parliament. Ian Murray has remained as the MP for the constituency since 2010, and is currently one of Scotland's longest-serving MPs. The 2019 general election was Labour's worst result in 84 years, with their lowest share of the vote recorded in Scotland since the December 1910 general election.
