Some MPs fear there is "more to come". Mr Kelly - a conservative MP from southern Sydney - has privately conceded he has no chance of retaining preselection in the face of a push by moderate Liberal members who have the numbers to remove him. Confidantes of Mr Kelly are urging him to quit the Liberal Party now to build momentum to run against Kent Johns - the presumptive Liberal candidate in Hughes - as an independent.

Mr Kelly could simply rejoin the Liberals after the election, Mr Ruddick suggested. Asked on Wednesday evening about Mr Ruddick's comments, Mr Kelly said quitting the party was "a future possibility" but he looked forward to contesting Liberal preselection on his record.

"I'm still very hopeful in a preselection contest. The only thing I would say is I would hope that any preselection process happens sooner rather than later," he said. "My 100 per cent concentration is on my job which is to represent my electorate until the end of this term." Loading A senior Liberal source confirmed the party was delaying the preselection in Hughes as long as possible in case Mr Kelly went rogue, but they would be forced to bring it forward if he quits and joins the crossbench. Mr Ruddick told Fairfax Media the war engulfing the Coalition would worsen and was in "a whole different dimension" to the woes that afflicted Labor under Kevin Rudd and Julia Gillard. "This is a philosophical and structural war," said Mr Ruddick, who is not presently a party member. "That’s why it’s going to only escalate post the two coming elections."

Ms Banks did not respond to a request for comment. Former frontbencher Craig Laundy, a close friend of deposed former prime minister Malcolm Turnbull who was deeply angered by the leadership coup, ruled out quitting the party but has not decided whether to recontest his Sydney seat of Reid. But NSW Liberal senator Jim Molan was so upset at being relegated to an unwinnable spot on the party's ticket he pulled out of a scheduled appearance on the ABC's Q&A, saying he could not defend the party at present.

He ruled out leaving the Liberal Party but told Fairfax Media: "All options other than changing parties are open to me." Prime Minister Scott Morrison will still attend the G20 meeting, which starts on Friday, while Finance Minister Mathias Cormann will fill in for Mr Frydenberg. However, Mr Morrison will no longer meet with US President Donald Trump. His office said it was not necessary as there were no pressing issues at the moment and he recently met with US Vice-President Mike Pence.
