OUTSPOKEN federal Nationals MP George Christensen is threatening to quit the Turnbull Coalition government and sit on the crossbench over a sugar dispute.

Mr Christensen said how he drafted a resignation letter after becoming furious about government inaction over a row between a foreign-owned sugar mill and cane growers in his Queensland electorate.

“If it takes ruffling a few feathers here, crossing the floor or going rogue to get an outcome, then you just have to do it,” he told News Corp.

Cabinet minister Christopher Pyne denied Mr Christensen had threatened to “go rogue” and described the news as a beat-up.

“George is not going anywhere, he is a valued member of the coalition and he is a great whip in the House of Representatives,” he told Nine Network.

“I can tell you that George Christensen is not going anywhere.”

Labor frontbencher Anthony Albanese used the report to point to weakness within Coalition ranks after senator Cory Bernardi quit to start a rival conservative party.

“You lost Cory Bernardi last week and this week you have George Christensen writing out his resignation letter ready to join the crossbench, which would cost you your majority on the floor of the House of Representatives,” he told Mr Pyne.

“I know that you can’t win votes now. Imagine how bad you could be if George Christensen sat on the crossbench.”
