QUEENSLAND'S opposition leader says Premier Campbell Newman should have pushed MP Scott Driscoll out of the Liberal National party, instead of letting him walk away from the party.
Mr Driscoll, the MP for Redcliffe, will sit on the crossbenches after resigning on Friday night, the day before he was likely to be expelled from the Liberal National Party.
Opposition leader Annastacia Palaszczuk says the real test for Mr Newman will be whether he accepts Mr Driscoll's vote when parliament resumes next month.
"Scott Driscoll walked before he was pushed," she told reporters in Brisbane on Saturday.
"It's the failure of the leadership of the premier that it was the [party] executive that was about to take action rather than the premier."
A spokesman for Mr Newman said as Mr Driscoll was now an independent MP it would be up to him to decide how he would vote.
"The Newman government will get on with tackling big issues like job creation, disability services and education reform," he told AAP.
Mr Driscoll is accused, among other things, of secretly controlling a community group in Moreton Bay from his electorate office and paying his wife tens of thousands of dollars in consultancy fees.
Ms Palaszczuk says he should front up to parliament and media to answer a number of questions that still remain unanswered.
"It's not good enough for the MP to be missing in action for months," she said.
She called Mr Driscoll's resignation letter "bizarre".
In the letter he lashed out at allegations against him.
"I supposedly sit there like Dr Evil and get confused between how many millions, billions or trillions are being made while stroking some hairless cat," he said.
"We've heard various utter rubbish allegations that I've basically exercised some sort of special Jedi Mind Control over people on private boards that I've never even sat on myself."
On his Facebook page, Mr Driscoll told his nearly 3,000 friends and supporters that he looked forward to continuing to serve as the MP for Redcliffe.
The Crime and Misconduct Commission is looking into claims of Mr Driscoll's involvement with the community group in Moreton Bay.
The Clerk of the Parliament and parliament's ethics committee are investigating allegations that Mr Driscoll misused his electorate office.
Comment has been sought from LNP President Bruce McIver.
Mr McIver announced on Saturday that nominations are open to replace Senator Barnaby Joyce if he is successful in his bid for the New England seat in the federal election this year.
Mr Driscoll could not be immediately contacted for comment.
