The Victorian Liberal MP who accused her party’s former leader of putting her in a headlock appears likely to be dumped.

It emerged last week that Moira Deeming had filed a police report claiming she was assaulted by Matthew Guy at a gala dinner on May 23.

Deeming accused Guy, a former state opposition leader, of grabbing her “violently” in a headlock. She has since claimed she misunderstood the meaning of headlock but refused to apologise for the allegations.

Last Thursday, Victoria Police said after reviewing CCTV footage of the incident that “there was no offence detected”.

Shadow attorney-general James Newbury said a decision on Deeming’s future in the Liberal Party was imminent.

“A request was made for her to make an unqualified apology. She has refused to do that,” Newbury said on Tuesday.

“Further action, therefore, needs to occur, and the party is working on that now.”

He said given Deeming’s clarification around the language used in her complaint, an apology wasn’t too much to ask.

“I think any good person would have apologised,” he said.

“Matt has gone through a very, very difficult few days, and the right thing would have been for an apology, an unconditional apology.”

In a statement, released on behalf of Deeming by her lawyer Tim Houweling, she said her complaint was made “honestly, in good faith and only as a matter of last resort”.

Houweling referred to CCTV footage that shows Guy sitting at a table and talking with Deeming and another man. Guy appears to place his hand on Deeming’s upper back or shoulder and pull her in to say something before making a similar gesture with the man.

The lawyer said Guy had kept his grip as Deeming tried to pull away, preventing her from freely moving her head for several seconds.

“Without attributing motive to the other party, our client maintains that from her perspective this physical contact by a senior male colleague in the workplace was unexpected, unwelcome, physically painful and caused her to feel fear and confusion,” he said.

Guy had demanded a public apology from Deeming and said his family name and reputation was “not a political toy”.

“There was no ambiguity. I did not do what was alleged. The CCTV proves this. It did from the start, and Victoria Police agree,” he said on Friday.

“Moira Deeming owes me a public apology.”
