Marc Bellemare said he realized while serving as a Liberal in cabinet that "the word of Jean Charest was worthless."
"For Jean Charest, the interests of the friends of the Liberal Party came before the interests of Quebecers," Bellemare told a news conference Friday in Sherbrooke.
Bellemare threw his support behind Parti Québécois challenger Serge Cardin, the former MP for the area.
Cardin said he was "honoured that Mr. Bellemare has confidence in me."Suggest a correction
