The Quebec Liberal Party (PLQ) has launched a website in which it attacks the credibility of the Coalition Avenir Quebec (CAQ) and its leader, Francois Legault. 

The website, testdecredibilite.com, "reports the promises of the CAQ and tries to demonstrate the impossibility of achieving them."

Ministers Dominique Anglade, Sebastien Proulx and Carlos Leitao are featured on the website in short videos. 

The videos cover a breadth of issues, including the CAQ's proposal that kindergarten begin at age 4, and an overall shortage of manpower. 

The Liberal Ministers ask CAQ party leader Francois Legault to answer questions and "stop hiding."

The CAQ has dominated public opinion polls for several months, making them the Liberals' main opponent in October's general election. 

At the opening day of the CAQ's convention on Saturday - which happened to also be Legault's birthday - the leader dismissed the website as "desperate."

"I think Mr. Couillard is desperate and I think Quebecers don't like the negative approach in politics," he said. 

He lumped Couillard in with the Parti Quebecois in terms of campaign tactics. 

"Lisee and Couillard, they are used to having a campaign where the only ballot question is about the sovereignty of Quebec, so right now they are a bit in a kind of panic," said Legault.
