The outspoken senator criticised the Liberal party on a national radio broadcast today for their failure to support fellow Liberal former home affairs minister Karen Andrews, who has called for Scott Morrison's resignation from parliament.

Ms Lambie said Andrews had stuck her neck out to get Morrison to resign after the revelation he had secretly held five portfolios as leader.

"And once again Liberal men are standing there on the other side not supporting her. I find it disgusting," Lambie said.

Ms Lambie also wondered about the future leadership of opposition leader Peter Dutton.

"If you think you're going to exist in three years' time, and you think this is acceptable behaviour, mate, you really need to go and have a good look at your leadership because this is not acceptable behaviour."

Former Prime Minister Scott Morrison has publically stated on Facebook that "in hindsight, these arrangements were unnecessary."

He is holding a press conference today.
