The scandal over parliamentary allowances has claimed another scalp in South Australia, with Adrian Pederick standing down from his role as state government whip.

Premier Steven Marshall says he spoke with Mr Pederick on Thursday and while the country MP believes all his Child Education Allowance Rules claims for accommodation are above board, he will step down from the whip’s position.

“He does this out of an abundance of caution,” the premier said.

On Sunday, two government ministers quit cabinet after admitting to mistakes with their allowance claims, while a third stood down for other reasons.
