MLA Karen McPherson joining the Alberta Party

Former NDP MLA Karen McPherson, who quit the governing party’s caucus to sit as an independent, has joined the Alberta Party. 
McPherson, the member for Calgary-Mackay-Nose Hill, left the governing NDP while citing the increasing polarization of Alberta politics.

The news is set to be officially released Monday.
