Clive Palmer says there are "no divisions" within his party and Jacqui Lambie has rejected reports she could break ranks saying only "morons" would dilute the Palmer United Party's power in the Senate.
News Corp is reporting Senator Lambie is at odds with fellow PUP senator Glenn Lazarus over the Senate leadership position.
Leader Clive Palmer sought to play down the report in Canberra on Thursday and said Senator Lambie is not hankering for Senator Lazurus's job.
"She's just a novice senator finding her way," he said. "There are no divisions in our party."
Senator Lambie said the speculation was just a "diversion from the Murdoch papers".
She denied she was after the Senate leadership and said titles did not matter to the PUP members.
"Why would I want to be Senate leader? We're all doing the same job," she said.
"What morons would separate when we have that sort of power in the Senate," she asked.
But Senator Lambie confirmed she was being wooed by other parties but Senator Lazarus warned anyone trying to get to Senator Lambie would have to get through him first.
"Jacqui and I are tighter than ever … we're rock solid," he said, appearing alongside his colleague.
Senator Lazarus said the report was a "load of rubbish" and had "no idea" who might have briefed the report to News Corp.
