The Scottish National Party (SNP; Scottish Gaelic: Pàrtaidh Nàiseanta na h-Alba [ˈpʰaːrˠtʰi ˈn̪ˠaːʃən̪ˠt̪ə nə ˈhal̪ˠapə]) is a Scottish nationalist and social democratic political party in Scotland. The party holds 60 of the 129 seats in the Scottish Parliament, and holds 9 out of the 57 Scottish seats in the United Kingdom House of Commons. It is represented by 414 of the 1,226 local councillors across Scotland. The SNP supports and campaigns for Scottish independence from the United Kingdom and for Scotland's membership in the European Union, with a platform based on progressive social policies and civic nationalism. Founded in 1934 with the amalgamation of the National Party of Scotland and the Scottish Party, the party has had continuous parliamentary representation in Westminster since Winnie Ewing won the 1967 Hamilton by-election. In the February 1974 election it scored 22% of the vote and 30% in the October election of the same year, but only notched 7 seats in the former and 11 in the latter of 72 Scottish seats up for election.
With the establishment of the devolved Scottish Parliament in 1999, the SNP became the second-largest party, serving two terms as the opposition to a Labour-Liberal Democrat coalition. The SNP gained power under Alex Salmond at the 2007 Scottish Parliament election with 45% of the vote, forming a minority government, before going on to win the 2011 Parliament election, after which it formed Holyrood's first majority government. After Scotland voted against independence in the 2014 referendum, Salmond resigned and was succeeded by Nicola Sturgeon. In the run up to the 2015 election, the SNP trebled its membership to 110,000 .The SNP achieved a record number of 56 seats in Westminster after the 2015 general election to become the third largest party but in Holyrood it was reduced back to being a minority government at the 2016 election. In the 2021 election, the SNP gained one seat and entered a power-sharing agreement with the Scottish Greens. In March 2023 Sturgeon resigned and was replaced by Humza Yousaf.
