Clive Palmer has formally lodged a defamation case against Queensland Premier Campbell Newman, seeking $1.1 million in damages.

Federal MP Clive Palmer is seeking more than $1 million in damages from the Queensland premier for allegedly defaming him.

The federal member for Fairfax has lodged papers in the Queensland Supreme Court.

Papers have also been served on Premier Campbell Newman through the Crown Solicitor.

Mr Palmer says the premier’s claims he tried to “buy” the Newman government are totally false and damage his integrity.

“These comments by Mr Newman can’t be allowed to go unchallenged,” he said.

Earlier on Wednesday, the premier seemed unfazed by legal action by the leader of the Palmer United Party.

Mr Newman refused to comment on whether it would be appropriate to use taxpayer funds to defend the case.

Mr Palmer is seeking $1.1 million in damages. If he wins the case, he has promised to give the money to a charity that works with public servants sacked by the Newman government.

Mr Palmer is seeking $355,000 for the seriousness of the allegations, the extent of publication and harm caused. He’s seeking another $750,000 for hurt suffered.

“The plaintiff claims compensatory damages for defamation to compensate for the distress and embarrassment caused,” the claim says.

Mr Newman has 28 days to respond to the claim.

Opposition Leader Annastacia Palaszczuk said she was concerned taxpayers’ money could be used to defend the claim.

“It’s about time the conservative parties in this state stop fighting one another,” she said.
