Sussan Ley has resigned as Minister for Health, Aged Care and Sport in the Turnbull government.
Ms Ley says she is confident that She has followed the rules, not just regarding entitlements but also with the ministerial code of conduct.
She says the ongoing intense media speculation “has made this an incredibly difficult week.”
Prime Minister Malcolm Turnbull said Ms Ley’s replacements would be announced next week.
Mr Turnbull said that Arthur Sinodinos would stay on as Acting Health Minister until then.
“Australians are entitled to expect that politicians spend taxpayers’ money carefully, ensuring at all times that their work expenditure represents an efficient, effective and ethical use of public resources,” he said.
