This page shows the results of leadership elections in the Saskatchewan Progress Party, formerly known as the Saskatchewan Liberal Party, covering the period from 1905 to the present day. All leadership contests in the Saskatchewan Progress Party have been determined by delegated conventions.

Liberal leadership convention, 1905

Developments, 1905-1926

Walter Scott resigned as premier and party leader in 1916, and was replaced by William M. Martin on October 20 of that year. Martin was selected by the Liberal parliamentary caucus; it is assumed that he was subsequently confirmed without opposition at a provincial Liberal convention.

Martin, in turn, resigned in 1922, and was replaced by Charles A. Dunning on April 5 of that year. Dunning, like Martin, was chosen by caucus; it is also assumed that he was later confirmed without opposition by the party.

Gardiner resigned as Premier and party leader in 1935 to enter the federal cabinet of W.L.M. King.
