Billionaire politician Clive Palmer has called for the clerk of the Senate to resign unless she is able to maintain impartiality, following a staff email she wrote implying Mr Palmer was a bully.

A leaked internal email sent to Senate staff on Thursday, and obtained by Fairfax Media, reveals clerk of the Senate Rosemary Laing warned staff not to tolerate ''unacceptable behaviour'' and made reference to the ''conduct of a member of the House of Representatives''.

While the email does not directly name the MP, it was widely reported two weeks ago that there was an altercation between Dr Laing and Mr Palmer, the member for Fairfax, over amendments to the carbon tax repeal bill.

Mr Palmer, leader of the Palmer United Party, was annoyed that the clerk would not distribute amendments put up by one of his senators, Glenn Lazarus.
