The Canadian province of Québec's opposition political parties have called for a public enquiry into a recent price-fixing scandal whereby two ex-VP's from alcohol monopoly, the Société des Alcools du Québec (SAQ) admitted being involved in kick-back scheme with French wine producers.

Both the Parti Québecois and the Action Démocratique du Québec want to establish whether political interference may have been involved.

The scheme led to higher prices being charged for wine, generating more profits for the government-owned SAQ.

The parties also allege a cover-up by the province's Liberal administration, given SAQ chairman Raymond Boucher was the campaign manager for premier Jean Charest's victorious 2003 provincial election.
