QUEBEC - Parti Quebecois leadership candidate Veronique Hivon is promising to introduce electoral reform if she becomes premier.

Hivon says changes need to be implemented to take into account the percentage of votes garnered by each party represented in the national assembly.

She did not specify which system she prefers.

Hivon said today any electoral-reform changes would have to go to a provincewide referendum.

Hivon also wants more free votes in the legislature.

She and fellow former cabinet ministers Alexandre Cloutier and Jean-Francois Lisee are the three declared candidates so far in the race to succeed Pierre Karl Peladeau as permanent PQ leader.
