The 18th Legislative Assembly of Saskatchewan was elected in the Saskatchewan general election held in June 1975. The assembly sat from November 12, 1975, to September 19, 1978.[1] The New Democratic Party (NDP) led by Allan Blakeney formed the government.[2] The Liberal Party led by David Steuart formed the official opposition. Edward Malone replaced Steuart as party leader in 1976.[3] After the Progressive Conservative Party won two by-elections and convinced two Liberal members to defect[4] in 1977, the Progressive Conservative Party led by Richard Lee Collver shared the role of official opposition with the Liberals.[3]
John Edward Brockelbank served as speaker for the assembly.[5]
