Premier Kathleen Wynne has called a byelection for Feb. 5 in Sudbury, Ont., to replace a New Democrat who quit after just five months on the job.
The byelection has already split Liberal ranks in Sudbury after the party's candidate in last June's general election, Andrew Olivier, said he was asked by Wynne to step aside because she had another candidate in mind.
Wynne had said she hoped Olivier would stay with the Liberal team, but he has announced he'll run as an independent candidate.
The Liberals convinced New Democrat MP Glenn Thibeault to quit the NDP and be their candidate in the byelection.
Wynne has denied accusations from Olivier that Liberal officials promised him an appointment to get him to step aside for Thibeault.
New Democrat Joe Cimino, who beat Olivier by less than 1,000 votes in June, surprised supporters in November when he quit the legislature for personal reasons.
