WINNIPEG — Manitoba Premier Greg Selinger will have to put up money in his attempt to hold onto the leadership of the provincial NDP.

Rules released by the party say all leadership candidates, including the premier, will have to pay a $2,000 fee to run.

Selinger and any other candidates will also have to fill out a nomination form with signatures from at least 50 supporters.

Selinger is fighting off an internal leadership challenge and the NDP has scheduled a leadership contest for March 8.

There are no other candidates so far, but Theresa Oswald, a former cabinet minister who questioned Selinger’s leadership, has said she is considering it.

Selinger and the NDP have faced public anger over last year’s increase in the provincial sales tax, and recent opinion polls suggest support for the party has plummeted.
