Socialist Party

The Socialist Party (French: Parti socialiste [paʁti sɔsjalist], PS) is a centre-left to left-wing political party in France. It holds social democratic and pro-European views. The PS was for decades the largest party of the "French Left" and used to be one of the two major political parties under the Fifth Republic, along with the Rally for the Republic in the late 20th century, and with the Union for a Popular Movement in the early 2000s. It is currently led by First Secretary Olivier Faure. The PS is a member of the Party of European Socialists, Progressive Alliance and Socialist International.

The PS was founded in 1969 from a merger of the French Section of the Workers' International (SFIO), the Convention of Republican Institutions led by François Mitterrand, and other groups. In the 1970s, the PS surpassed the Communist Party's share of the left-wing vote. It first won power in 1981, when Mitterrand was elected president. The PS achieved a governing majority in the National Assembly from 1981 to 1986, and again from 1988 to 1993. PS leader Lionel Jospin lost his bid to succeed Mitterrand as president in 1995 to conservative Jacques Chirac, but he served as prime minister in a cohabitation government from 1997 to 2002, when he was again defeated by Chirac in the presidential election.
