Frank Klees is the first contender to officially enter the race for the Ontario Progressive Conservative leadership.

The Newmarket-Aurora MPP, who also ran against outgoing leader John Tory in 2004, formally declared his intent on Sunday.

"I look forward to what I know is going to be an exciting campaign over the next 90 days," Klees said. "I'll talk about the importance of returning to Progressive Conservative values and principles."

He added his 25 years in business and 14 years in the provincial legislature make him the best choice for a party seeking decisive leadership and energy. Klees held several cabinet posts in the Mike Harris and Ernie Eves governments.

Fellow MPPs Randy Hillier, Tim Hudak and Christine Elliott coyly hinted at entering the race in Chesterville on Saturday and are all expected to make announcements soon.
