Saskatchewan Progress Party

The Saskatchewan Progress Party (SPP) is a liberal political party in the Canadian province of Saskatchewan. It was founded in 1905 as the Liberal Party of Saskatchewan, and retained that name until members voted to change it in 2023. Until 2009, the party was affiliated with the Liberal Party of Canada.

The Liberals were a dominant force in Saskatchewan politics during the first half of the twentieth century, forming government for all but five years between 1905 and 1944. With the emergence of the Co-operative Commonwealth Federation (CCF) under Tommy Douglas' leadership, the Liberals spent the following two decades in Opposition before forming two more consecutive majority governments from 1964 to 1971. However, the party lost influence in the latter stages of the twentieth century. Although it reached Opposition status again in the mid-1990s, even that term was disrupted when much of the caucus abandoned the party to form the new Saskatchewan Party in 1997. The 1999 election marked the last time any Liberals were elected to the Legislature.
