Labour currently hold 22 of 129 seats in the Scottish Parliament and two of six Scottish seats in the European Parliament. Labour won the largest share of the vote in Scotland at every UK general election from 1964 until 2015, where they lost heavily to the Scottish National Party; every European Parliament general election from 1979 until being defeated by the SNP in 2009; and in the first two elections to the Scottish Parliament in 1999 and 2003. After these, Scottish Labour entered a coalition with the Scottish Liberal Democrats, forming a majority Scottish Executive.
In a landslide defeat at the 2015 UK general election, Scottish Labour was reduced to a single Member of Parliament, losing 40 of its 41 seats to the SNP, the first time the party had not won the largest number of seats in Scotland since 1959. In the 2016 Scottish Parliament election, Scottish Labour lost 13 of its 37 seats, becoming the third-largest party for the first time after being surpassed by the Scottish Conservative Party. At the most recent general election in 2017, Labour won 7 seats in Scotland—improving on its performance two years previously—with 27.1% of the vote, and was the third-largest party behind the SNP and the Conservatives.
The Scottish Labour Party is registered with the UK Electoral Commission as an Accounting Unit (AU) of the UK Labour Party and is therefore not a registered political party under the terms of the Political Parties, Elections and Referendums Act 2000.
The Scottish Labour Party is administered by the Glasgow-based Scottish Executive Committee (SEC), which is responsible to the Labour Party's London-based National Executive Committee (NEC).
The Scottish Executive Committee is made up of representatives of party members, elected members and party affiliates, for example, trade unions and socialist societies.
