Victorian Labor wants Shaw out of parliament

Victorian Opposition Leader Daniel Andrews says he'll push to have balance-of-power MP Geoff Shaw expelled from parliament and won't do deals with the independent.

Should Mr Shaw be found in contempt of parliament for misusing his parliamentary car and expelled from parliament, then Mr Andrews says the independent MP's call for a no-confidence vote against the Napthine government is no longer relevant.

"I'm not prepared to have Geoff Shaw run our state," Mr Andrews told reporters on Wednesday.

Mr Andrews will move to have Mr Shaw found in contempt and expelled when parliament resumes on Tuesday.

He said a by-election could be held in Mr Shaw's seat of Frankston as early as July 12 or 19.

"If there is the votes on the floor of the house to expel Mr Shaw then we can deal with him once and for all and we can end this circus, we can end this chaotic, dysfunctional, just nonsense that holds us back and I think damages our state," Mr Andrews said.

"If I have my way, if there's a majority on the floor of the house, then Geoff Shaw will not be in the parliament any longer.

"Therefore discussions about confidence arising from Mr Shaw's lack of confidence in the premier are no longer relevant."

But Mr Andrews would not rule out Labor moving a vote of no confidence against the coalition government at any time.

"I'm not going to be doing deals with Geoff Shaw. I want Geoff Shaw out of the Victorian parliament."

Mr Andrews said it would be up to Liberal members of parliament, including the premier, to support the motion when the opposition raises it on Tuesday.

He said the motion would ask to find Mr Shaw in contempt of parliament over misusing his taxpayer-funded car, with the penalty of expulsion attached to that.

He said he did not think it was a waste of taxpayer money to go to a by-election months out from the November 29 state poll.

Mr Shaw, the Liberal-turned-independent MP who holds the balance of power in the Legislative Assembly, threatened the stability of the parliament by saying he would back any Labor no-confidence motion against the Napthine government.

Premier Denis Napthine said he would not be held to ransom by Mr Shaw, rejecting his demand for an absolute assurance from the government that the parliament would not seek to sanction him further.

The coalition-dominated parliamentary privileges committee found he breached the MP code of conduct but a minority report from its Labor members went further and recommended the independent MP be found in contempt of parliament.
