Liberal MP Angus Taylor has urged Malcolm Turnbull to throw his support behind the democratic reform of the party's NSW branch, warning it needs to come now.
Speaking to Lateline, the Assistant Minister for Cities said the party could not afford to wait after its performance at July's election.
"The Prime Minister Malcolm Turnbull wants to see an energised and a motivated membership base in NSW … we all want that," he said.
"And if that's the objective, my point is, democratic reform … giving more power to the membership base, the ability to vote for their local representatives, is the solution to that problem."
In a speech to the Sydney Institute last night, Mr Taylor warned the Liberal Party would face "oblivion" unless more power was given to its rank and file members to vote on preselection.
Earlier today, former prime minister John Howard told the National Press Club there was a view among Sydney Liberals that preselections in safe seats were "near to a closed shop".
He said he agreed with Mr Taylor that the preselection system needed to be altered, adding it would take the support of both the Prime Minister and NSW Premier Mike Baird to make it happen.
"It needs their influence to bring about change, it won't happen otherwise," he said.
'We can't wait for change': Taylor
In January, the ABC reported Mr Taylor was one of several MPs targeted by powerbrokers within the NSW Liberal branch, who were planning to unseat sitting members during preselection.
It was understood Mr Taylor received a phone call from Mr Turnbull at the time expressing his support.
When asked if Mr Turnbull had indicated whether he would help drive the reform in the NSW branch, Mr Taylor told Lateline the Prime Minister had "indicated to everybody … he wants an energised Liberal Party in NSW".
"With the support of people like John Howard — Arthur Sinodinos has made it very clear what his views are on this — Mike Baird and others, and the view that the Prime Minister wants to see an energised membership base, I'm confident that these changes should and will happen in time, and it needs to be relatively quickly," he said.
"We can't wait for this, we do need now a membership base who are readily out there barracking for us."
The Hume MP said he did not agree with former party member John Ruddick, who earlier told the ABC that Mr Turnbull had been a "strident campaigner against democratic reform".
"I don't think that's right," Mr Taylor said.
He also denied the problems within the NSW branch stemmed from a factional divide within the Liberal Party.
"In any organisation, there's groupings of people who work to further their interests," he said.
"The system's responsible for it. We have a system that allows power to be centralised … so the drawbridge can be brought up."
