Alberta Premier Jim Prentice says a PC election candidate convicted of soliciting a prostitute is acceptable because he owned up to what he did.

Speaking on a provincewide radio talk show, Prentice said Mike Allen took responsibility and pleaded guilty after he was caught in a sting operation while on government business in Minnesota in 2013.

Allen is the incumbent MLA for Fort McMurray-Wood Buffalo in next Tuesday's election.

"I've put it behind me and have moved on," said Allen. "The vast majority of my constituents have. It's very rare for me to get a response at the door ... I think in the last two and a half weeks I've had two people bring it up."

But Prentice said the party was correct in disqualifying Jamie Lall as a candidate in Chestermere-Rocky View, because Lall once had a restraining order against him in relation to his former girlfriend.

Prentice said the restraining order alone was enough to disallow Lall, but the other factor was that Lall refused to tell the party.

Lall has said he did tell the Progressive Conservatives about it.
