New Democrat MLA Leonard Krog has announced he will be running for the mayor's seat in Nanaimo October 21st.
The move could potentially upsetting the delicate balance of power for the provincial government.
If Leonard Krog is elected in October, the NDP and Green alliance reduces to 43 seats, while the B.C. Liberals have 42.
Speaker Darryl Plecas sits as an Independent, after being booted from the Liberal caucus last year.
The departure of an NDP member of the legislature could have significant implications for the New Democrats which, with help from three members of the Green party, hold on a razor-thin majority in the legislature.
