The Parti Québécois has adopted a plan to lower the voting age to 16 and introduce citizen-led referendums in Quebec if elected to government.

The two policies are part of a series of measures approved by the provincial opposition party's delegates at a meeting this weekend in Montreal.

The proposal to lower the legal voting age has long been debated within the PQ and young people are traditionally among the sovereignty movement's strongest supporters.

The introduction of citizen-led referendums would mean future votes on Quebec's independence could be triggered by popular demand.

The proposal was led by a prominent MNA who argued that if 15 per cent of Quebecers signed a petition to hold a referendum on any topic, there could be one.

PQ Leader Pauline Marois closed out the convention with a speech Sunday afternoon.

Leadership stabilizes, for now

After weeks of speculation, Marois now appears set to lead the PQ unopposed into the next election.

Former Bloc Québécois chief Gilles Duceppe had been her rumoured replacement until he announced last weekend he wasn't going to return to active politics amid accusations he mishandled public funds.

A new opinion poll released Saturday suggested the recent infighting at the PQ hasn't hurt their standing with voters.

The party polled a close third behind Premier Jean Charest's Liberals and the Coalition for Quebec's Future (Coalition avenir Quebec), a new party which continues to lead the polls.
