Sussan Ley resigns after travel probe

Federal Health Minister Sussan Ley has resigned from the frontbench following disclosures that she used taxpayer-funded trips to buy property and attend New Year's Eve functions.

Prime Minister Malcolm Turnbull announced Ms Ley's resignation on Friday afternoon, after receiving the findings of an investigation into her travel claims from the secretary of his department.

He refused to reveal the findings, telling reporters in Sydney her decision to resign was the "right judgment".

"She has made a judgment that is, I believe, in the interests of the government and she has made an appropriate judgment, and I do want to say that I thank her for her service over many years."

Ms Ley stood aside as health minister on Monday, dismissing the scandal as a distraction and insisting she had broken no rules.

She was hopeful of returning to the portfolio but faced growing calls
