Another MLA has put their support in behind Gary Mar's campaign to take on the leadership of Alberta's PC party.

Jonathan Denis, a Calgary cabinet minister who was a vocal supporter of Mar's opponent-turned-supporter Ted Morton says he his behind Mar.

Ted Morton announced his support for Gary Mar on Monday had encouraged his own supporters to follow suit.

Denis says the decision was difficult, but it was important for him to pick a side. "I think at picking nobody is rather indecisive and I think that's what makes people often cynical about politics when you sit on the fence. I think it was time to take a stand on where my vote was going to be going as have some other people in the Morton campaign."

Denis attributes Mar's pledge for a balanced budget as the main reason he chose to endorse him.
