A federal government staffer has resigned after wild scenes erupted with another Young Liberal over the ousting of former PM Tony Abbott.

A staffer to Parliamentary Secretary Concetta Fierravanti-Wells, and a staunch Abbott-supporting conservative, Jakov Miljak, allegedly grappled with Turnbull-backer, James Camilleri, at a Young Liberals meeting in Sydney on Tuesday night.

According to Fairfax Media, Mr Miljak wrestled with Mr Camilleri in a “push punch” incident against the wall of the meeting room.

“The whole room had to stop. They were dragged apart by their colleagues,” the source said.

There was more than 100 people who witnessed the altercation at the function held at City Tattersalls Club on Pitt Street, Sydney.

Ms Fierravanti-Wells told ABC radio on Friday that she didn’t think it was appropriate behaviour and accepted Mr Miljak’s resignation.

“The Young Liberal council always has its moments, but when I became aware of this I spoke to the young man in question,” she said.

“People have different views in relation to the party, and the Liberal tradition versus the Conservative tradition has made our party a strong one.”

This comes as Ms Fierravanti-Wells is tipped to be promoted within the new government line-up, after Malcolm Turnbull took over as Prime Minister on Monday.

According to Fairfax Media, an official complaint was lodged to the NSW Liberal Party.

A spokeswoman for director Tony Nutt refused to comment.
