Queensland's Liberal National Party (LNP) is playing down reports of a secret recording of party hierarchy offering MP Bruce Flegg an inducement to quit Parliament.

Dr Flegg, the Government's former housing minister and now a LNP backbencher, has refused to confirm if he secretly recorded party officials discussing how to parachute Premier Campbell Newman into state politics.

The Crime and Misconduct Commission (CMC) has previously found no evidence that Dr Flegg was offered an inducement to quit his Brisbane seat of Moggill to make way for Mr Newman, the then-Brisbane mayor.

But the Courier Mail newspaper has today published secret recordings outlining lucrative job offers in the US, London and Asia.

The offers were allegedly made through former LNP treasurer and now federal senator in-waiting, Barry O'Sullivan.

It is claimed there is another taped conversation in which Mr O'Sullivan and party hierarchy discussed asking the Member for Aspley, Tracy Davis, to retire to make way for Mr Newman.

'No wrongdoing'

Dr Flegg says he did not supply the recording to the newspaper and matters relating to this morning's claims are subject to a police investigation.

He says he will cooperate fully with authorities if required.

Ms Davis, now the state's Communities Minister, also declined to comment today on the claims.

LNP state president Bruce McIver said in a statement today the allegations had already been investigated by the CMC, which found no evidence of wrongdoing.

Queensland Attorney-General Jarrod Bleijie says people have had enough of political sideshows.

Mr Bleijie says the latest claims are just another unnecessary distraction.

"I think Queenslanders and Australians are sick and tired of the sideshow alley politics that we've seen in the last few days," he said.

"Add that again to this list as being investigated by the CMC and that's all I have to say on it."

'Fresh evidence'

However, Opposition Leader Annastacia Palaszczuk says the latest scandal to rock the LNP is the most serious since the election of the Newman Government.

Ms Palaszczuk wants the matter reinvestigated.

"Everybody knew what was going on and now there's fresh evidence," she said.

"If a person has mislead the CMC, if a person has lied to the CMC - this is perjury.

"Perjury means a maximum of up to 14 years' imprisonment.

"These are serious serious allegations that now must to be reopened and reinvestigated."

But Police Minister Jack Dempsey says there has been no complaint to police.

"I do encourage anyone - whether it be from a political party or a media organisations - to please bring those matters before the proper authorities," Mr Dempsey said.

Premier Campbell Newman says the allegations have already been investigated and dismissed by the CMC.

"The independent crime fighting body will do their job," he said.

"They cleared these people before - if this is new material, and it doesn't seem to be in my view, but if it is new material I'm sure that they will act upon it."
