Prime Minister Tony Abbott has attacked his own government colleagues for speaking out against Chief of Staff Peta Credlin, labeling the criticism sexist and based on the fact she is a woman.
Government members have been complaining to journalists in recent weeks about the way Ms Credlin runs the Prime Minister's office, claiming that she has too much control.
It has led to damaging stories about internal rifts and about how Ms Credlin needs to take some responsibility for the government's falling popularity.
