THIS is one zinger which might really turn up the heat - Bill Shorten has told a press conference Malcolm Turnbull should quit.
"Mr Turnbull proposed Senate reform. He's made a bad situation even worse," Mr Shorten said.
"How on earth did Mr Turnbull think than an idea of reform could end up with two or three One Nation senators in the Senate?
"This is farcical.
"Mr Turnbull clearly doesn't know what he's doing. Quite frankly, I think he should quit.
"Malcolm Turnbull is the reason why One Nation is back in the Senate after 18 years. This guy is not up to his day job. He doesn't know what he is doing, has lost the confidence of his party."
The comments come as a down-to-the-wire count to decide the shape of the country's 45th parliament is finalised.
