IPSWICH West MP Sean Choat says he has no intention of resigning from the LNP over his stance on asset sales.
Mr Choat dropped a bombshell in Thursday's QT when he said he would be prepared to cross the floor in future if the government attempted to sell electricity, water or transport assets.
In response, Bundamba MP Jo-Ann Miller said Mr Choat should resign as his views were opposed to that of the LNP.
"But I have no intention of resigning," Mr Choat said.
"In my party I can express myself. In her party, you cannot.
"My colleagues understand my stance, and at least as a member of the LNP I can use my conscience."
But Mrs Miller said Mr Choat's comments were " just aimed at publicity and he doesn't really believe what he is saying".
"If he really believes what he says, he should resign," she said.
"He should tender his resignation to Campbell Newman in the LNP party room on Monday and I am sure that many LNP MPs will follow him.
"Ian Berry, Ian Rickuss and other people I am sure would take the lead from Sean Choat in resigning from the LNP on the asset sales issue.
"Otherwise they have no hope of winning their electorates at the next election."
Mr Choat said he welcomed the praise of the Electrical Trades Union (ETU) for his stance on asset sales after they put out a media release to that effect.
"That is very nice," he said.
"My stance goes back to my days in the railway and the commitment I made in 2012. The good thing is that the government has made the commitment that they won't do anything without consulting the people, unlike what the last lot did
"As for Jo-Ann Miller. How do you spell hypocrisy? ALP.
"She was part and parcel of those (2009) asset sales and she should be ashamed of herself."
