On the eve of Manitoba's next premier being sworn in, her opponent is asking for the ceremony to be delayed.

On Saturday, MLA Heather Stefanson was named PC leader in a tight race, winning 51 per cent of the ballots, by 363 votes over Shelly Glover.

Stefanson is set to be sworn in at 2 p.m. on Tuesday.

Glover, who would not concede Saturday, has now asked lawyer Dave Hill to represent her as she challenges the results.

"I will shortly be seeking an Order of the Court of Queen’s Bench declaring that the election results are invalid and requiring a new vote," Hill writes to Lieutenant Governor Janice Filmon. "I would respectfully request that you defer the swearing-in of a new Premier of Manitoba until the Court has ruled on this matter."

Last week Glover has raised concerns about ballots in the PC election, saying that many party members had not received a mail ballot.

"From the information given to me, there would appear to be substantial irregularities affecting the result, in the counting of votes," Hill says in the letter.

On Saturday, PC Caucus President Tom Wiebe detailed the voting processes, saying they were “very far away from inept or disorganized" and they visited rural locations and set up voting sites after learning some people did not receive their ballots. He at the time he said there were 82 spoiled ballots and 17 that are disputed.

"I look forward to seeing Manitoba’s first female Premier take the oath of office. My long-time friend and colleague Heather Stefanson will serve Manitobans well with her abundance of experience, intelligence and compassion. Manitobans have much reason for optimism," Premier Kelvin Goertzen says in his resignation letter Monday to Filmon.

Glover said on Saturday that "the results are the results" that night, but Sunday was another day.

"I know many of you drove two or three times too many locations to get ballots," Glover says Saturday, addressing people who may disagree with the election results. "I so believe that members deserve a chance to not only have a choice but also a voice. I would hope that our new premier and her team look at this race and find improvements in this party because this party must change."

Heather Stefanson says she told Shelly Glover "we are going to unite this party together" as she and Glover embrace after the results were called.Heather Stefanson says she told Shelly Glover "we are going to unite this party together" as she and Glover embrace after the results were called.
