Palmer United Party leader Clive Palmer says he will file a defamation lawsuit against Queensland's health minister shortly after the weekend's election.
The outspoken mining magnate used Twitter to announce on the weekend that he would sue Lawrence Springborg "for defamation for comments he made about me".
He told AAP on Monday that he would not reveal details of the alleged defamation as it was a "private matter" that would soon be before the court.
Mr Palmer said he intended to lodge the lawsuit early next week, after Queenslanders go to the polls on January 31.
The impending lawsuit has come to light just days after several senior Liberal National Party figures - including Premier Campbell Newman and Mr Springborg - launched their own writs against radio shock jock Alan Jones.

Mr Palmer had earlier offered financial support to Mr Jones to fight any legal action against him by Mr Newman.
Jones is facing defamation action over comments about Queensland's New Acland coal mine.
The broadcaster also claimed Mr Newman lied to him by pledging that stage three of the Acland project, on the Darling Downs, would not proceed but then approved it anyway.
AAP is seeking comment from Mr Springborg.
