Queensland premier Annastacia Palaszczuk has threatened to sue Katter’s Australian Party leader, Robbie Katter.

Katter says Palaszczuk’s lawyers sent him a letter, calling for an apology and a retraction of statements he made calling for the Premier to be charged over threats made to cut additional staff funding after they refused to denounce Senator Fraser Anning’s “final solution” speech.

Katter’s comments come after the Crime and Corruption Commission found the Premier’s comments “exposed her to the prospect of facing a charge of bribery,” but that there was “no reasonable prospect of a successful prosecution.”
