QUEBEC -- Philippe Couillard's Liberals won two provincial by-elections on Monday in what some viewed as an early showdown between the premier and Parti Quebecois Leader Pierre Karl Peladeau.

One of the ridings was Jean-Talon, a Quebec City riding the Liberals have held since 1966.

The other by-election in the provincial capital saw one former TV reporter, Veronyque Tremblay, defeat ex-journalist Jocelyne Cazin, who was running for the Coalition for Quebec's Future.

Sebastien Proulx easily won in Jean-Talon, getting about 40 per cent of the votes, compared with the 44.5 per cent garnered by Yves Bolduc in the 2014 general election.

In Chauveau, Tremblay snagged about 40 per cent of the vote to emerge victorious with a majority of more than 1,500 votes.

In comparison, the Coalition's Gerard Deltell won the riding in 2014 with 52.4 per cent of the vote and a majority of nearly 10,000 over the Liberal candidate.

Deltell stepped down earlier this year after announcing he will run for the federal Conservatives in the fall election.

Late in the Chauveau campaign, the PQ sent in Peladeau's longtime partner and well-known TV personality, Julie Snyder, to boost the chances of candidate Sebastien Couture.

He ended up with about 16 per cent of the vote.

The results will have little impact on the makeup of the national assembly: the Liberals now have 71 of the 125 seats, compared with the PQ's 30, the Coalition's 21 and Quebec solidaire's three.
