Ryan Meili, NDP MLA for Saskatoon-Meewasin, announced Thursday that he will seek the party's leadership for the third time in less than a decade.
Meili announced his decision after the spring sitting of the Legislature adjourned.
The Saskatoon doctor ran for the party's leadership in 2009, losing to Dwain Lingenfelter, and again in 2013, when he lost to Cam Broten by just 44 votes.
Both Lingenfelter and Broten went on to lose their own seats in the subsequent provincial elections, sparking another leadership race for Saskatchewan New Democrats.
Party members will elect their new leader in Regina next May.
