Labor leader Bill Shorten today highlighted the secret Coalition deal between the Liberals and the Nationals which gives the Nationals that extraordinary power.
Australian Deputy Prime Minister Barnaby Joyce has resigned following several weeks of sustained media coverage surrounding his extramarital affair.
"I acknowledge your concerns, however it should also be said that you don't have a Federal member of Parliament in the National Party of Australia, your last member spending time nearly exclusively as an independent and only once or twice coming to the National Party room meetings".
And on occasion, as with Mr Joyce and Mr Turnbull, the leader and deputy don't always get on.
National MPs are becoming increasingly concerned about the fallout from Mr Joyce's affair with his former media advisor, Vikki Campion.
The under-fire Mr Joyce called a press conference in Armidale at 4pm NZT.
Federal party director Ben Hindmarsh said the complaint would be taken seriously, treated with strict confidentiality and given due process.
When his staff said there was only one question left, Mr Turnbull declined to say if he still supported the Nationals leader who is now facing historical allegations of sexual harassment and a potential leadership spill.
Joyce said he couldn't "enter any discussions" about recently allegations of sexual harassment laid against him.
"They should have been referred to police if they had substance", Mr Joyce said.
Freed from Cabinet restraints, Abbott has criticised Turnbull's policies from the backbench, although Joyce said he would not destabilise the government.
Despite standing down as deputy PM, Joyce said there was not "a shadow of a doubt" that he would run for re-election in New England.
The National Party will now elect a new leader, who will also become deputy prime minister under the terms of the coalition agreement with Turnbull's Liberal party.
