Social Democratic Party

The Social Democratic Party (SDP) is a political party in Australia. The party has been in government as the primary party within multiple coalitions at the federal level. NGSpy is the leader of the party since January 2020.

History
The Social Democratic Party was formed on 2 October 2018 as a result of the faction breakup of the Australian Labour Party. The leader, Youmaton, spilled her Social Democrats faction off to form the Social Democratic Party. The party at founding was primarily comprised of the membership of the ALP faction. It entered Parliament with both lower and upper house representation, quickly becoming the dominant party in opposition with Youmaton remaining the Leader of the Opposition. On 12 October 2018, the Australian Unity Party merged into the party.

December 2018 federal election
The party entered Government at its first federal election contest in December 2018. As the party was the dominant party of the Left Coalition, commanding 6 seats in the lower house, Youmaton took the office of Prime Minister. Around a month after the election, the Radical Party merged into the SDP.

March 2019 federal election
After Prime Minister Youmaton called an early election due to government instability, the SDP surged to 9 seats (1 short of a majority) in the House of Representatives. The SDP soon begun negotiations with the United Democratic Party to form government, and by the end of the day had established the Third Youmaton Ministry.
