MP has no conflict of interest: Newman

Queensland's Integrity Commissioner has given a government MP the nod to take part in a multimillion dollar project, the premier says.

Leader of the House Ray Stevens told parliament on Thursday he's investing in and advising a $100 million cable car proposal in the Gold Coast hinterland.

Mr Stevens, who's also the Assistant Minister for e-Government, says he received advice from the Integrity Commissioner giving his involvement the green light.

The MP is a key government member, but Mr Newman says there won't be any conflict of interest.

"I reject that, and again I go back to the integrity commissioner, I'm sorry that is what I base it on, not some other esoteric view on what a conflict of interest is," he said.

"I base it on the professional advice of the integrity commissioner, which has given him a full green light to do this, as long as he makes sure that he is very clear and up front."

But the premier's claim can't be verified as Mr Stevens won't publicly release the advice.

Mr Newman was asked if he would encourage more of his MPs to pursue more entrepreneurial activities.

"It would be a sad day indeed in 2014 if nobody from the business world could be involved in state politics, or federal politics, or local government," he replied.

Comment has been sought Mr Stevens.
