Miner and federal MP Clive Palmer says his lawyers are due to serve deputy premier Jeff Seeney with defamation papers on Tuesday.

Clive Palmer’s lawyers are due to serve Queensland’s deputy premier Jeff Seeney with defamation papers on Tuesday.

The mining magnate and federal MP is already suing Premier Campbell Newman for defamation for claiming he tried to “buy” the Queensland government.

He will now lodge a defamation case against Mr Seeney, for alleging he sought special favours for his Waratah Coal interests in the untapped Galilee basin.

Mr Palmer, a former Liberal National Party life member, didn’t say what damages he’d seek from Mr Seeney, but if his suit was sucessful any compensation would be donated to charity.

“It (the serving of papers on Mr Seeney) is supposed to be today,” he told AAP.

Mr Seeney last week forwarded all paperwork his office and the government had with Mr Palmer to the Crime and Misconduct Commission, but stopped short of making a formal complaint.

He said the impending defamation action wasn’t a surprise.

“This is what we’ve come to expect from Mr Palmer,” Mr Seeney told AAP.

“Mr Palmer sues everyone.”

Mr Seeney alleges Mr Palmer sought favourable treatment in April 2012 for Warath Coal.

However, Mr Palmer has said his Galilee rail proposal would not have favoured Waratah Coal and would have ensured open access to infrastructure for every company operating in the basin in western Queensland.

In March 2013, the government announced Indian mining giant GVK and Gina Rinehart’s Hancock Coal would work with freight rail company Aurizon to build rail infrastructure from the basin to the Abbot Point coal terminal near Bowen.

Mr Seeney declined to say if he or the taxpayers would be funding the defamation case brought by Mr Palmer.

“I have no idea what Clive Palmer has done,” he told reporters.
