Parti Quebecois calls for former premier's appearance in front of legislature committee

The Parti Quebecois is calling for former Quebec premier Jean Charest to appear before a legislature committee amid media reports he's being investigated by the province's anti-corruption unit.

The unit is reportedly probing whether engineering and construction firms contributed to the Quebec Liberals between 2003 and 2013 in return for contracts and subsidies from the Charest government.

Charest was premier between 2003 and 2012.
