Jacques Parizeau says the Parti Quebecois must change radically and make a clear commitment to achieve independence one day.
Writing in Le Journal de Montreal, the former PQ premier says the party must stop believing that talking about soverignty publicly costs votes.
He adds it must be up front on the subject, even during an election campaign.
Parizeau also says Quebec has changed and that the PQ must change, too.
He points out the approach to building an independent Quebec is different than it was 20 or 30 years ago, that it requires a lot of preparation, studies, explanation and promotion.
