Senator Rodney Culleton has stormed out of a Federal Court hearing over a broken land deal debt in the latest bizarre episode for the WA farmer.

He complained that two men were present in court against whom his wife has taken out violence restraining orders.

The two men, farmers Bruce Bell and Frank Bertola, once fought the banks alongside Senator Culleton but are now trying to challenge his eligibility as an MP.

Senator Culleton quit the One Nation Party overnight.

Senator Culleton had refused to go back in to the court after walking out, where he is challenging a court order that he pay former Wesfarmers director Dick Lester $280,000.
