A "heated exchange" between two Victorian Labor MPs in a members-only dining room has sparked a parliamentary probe.
The minister for sport, major events and veterans' affairs, John Eren, and former minister Adem Somyurek were involved in the confrontation on Wednesday.
"There was an incident that took place last night and I've reported that to the presiding officer," Mr Eren told parliament.
Speaker Colin Brooks had earlier announced a parliamentary investigation, which Mr Ered said made it "totally inappropriate" to comment further.
Opposition Leader Matthew Guy launched an attack on Mr Eren, accusing him of assaulting Mr Somyurek and drinking beforehand.
"I absolutely refute the allegations that have been made by the leader of the opposition," Mr Eren said.
Premier Daniel Andrews told parliament he would not ask Mr Eren to stand down.
Mr Somyurek was not in the Legislative Council when MPs gathered for question time on Thursday.
Upper house opposition leader Mary Wooldridge asked leader of the government Gavin Jennings if the ministerial code of conduct had been breached.
Mr Jennings said he had no firsthand information of what happened.
Upper house president Bruce Atkinson told MPs he would describe the incident as reported to him as a "heated exchange".
The mood in the chamber descended into a slanging match when Ms Wooldridge listed a series of scandals involving Labor MPs, calling them a "bunch of scandal-ridden abusive misfits".
