A government MP says the Queensland premier must explain misleading advice he gave to parliament about his removal from an ethics committee.
Alex Douglas says he'll make a statement in parliament on Wednesday, outlining very grave concerns he has about his removal as chairman of the committee.
He said Mr Newman's statement to parliament on Tuesday - that Dr Douglas was happy to move out of the role - "is untrue".
Dr Douglas says very concerning aspects have surfaced about his removal as chairman, and there are issues at play that go to the core of the government's integrity.
He called on the premier to set the record straight about his removal, and said he never wanted to leave the post in the first place.
He said he believed there was no other course of action but to reinstate him to the chairman's role.
"Under the circumstances, there's absolutely no other step that can occur," Dr Douglas said.
He called on others who might have had a hand in his removal to also be upfront about the circumstances.
"I think anyone else who participated in this needs to explain themselves too," the Liberal National Party MP said.
"I think that it appears there were other people involved in this decision, well before it was put to me on Monday morning."
Asked if he believed his removal was the result of an internal LNP fix, Dr Douglas said: "I don't know. I'm not absolutely certain of that."
"(Under) the circumstances that appear to me to have occurred, it is absolutely more imperative than ever that I not be removed from that committee and that I stay there."
He said developments he'd learned of overnight had troubled him deeply, but he would not go into specifics.
"Certain matters have come to light since all this occurred, particularly in the last 24 hours," Dr Douglas said.
"I don't want to state them at this point in time.
"I think the premier needs to clearly explain either who told him I wanted to leave ... they need to explain themselves."
He said Mr Stevens had called him.
"I said I didn't want to leave that position."
Dr Douglas said he advised Mr Stevens there was only one other candidate he believed was capable of leading the committee, which has been tasked with investigating Mr Newman's handpicked transport boss Michael Caltabiano.
Mr Caltabiano has been accused of misleading parliament about his relationship with Ben Gommers, son of Arts Minister Ros Bates, whose appointment to a plum transport job is under investigation.
Mr Stevens later told the ABC that Dr Douglas was being "loose with the truth" and he was losing confidence in Dr Douglas.
Asked who told the premier Dr Douglas wanted to leave the ethics committee, Mr Stevens said it was him.
"It was absolutely me 100 per cent. I didn't mislead the premier at all," Mr Stevens said.
"The premier is advised wholly and solely by me on these matters."
He said Dr Douglas was eager to take over the chair of the legal affairs and community safety committee after it was vacated by defecting MP Ray Hopper.
"He said 'yes, I will do that for you no problem'," Mr Stevens said of Dr Douglas.
Mr Stevens said he was "very rapidly" losing confidence in Dr Douglas.
"He talks about a lot of matters that are extraneous to his own interests and his expertise," Mr Stevens said.
"And I'm starting to think that maybe my judgment in putting him forward as chair of that committee may be a bit erroneous and I'm starting to question myself."
The premier's office said he would not be responding before parliament sits later in the day.
