Linda Reynolds extends her leave following Brittany Higgins allegation

Defence Minister Linda Reynolds will remain on sick leave for another month, amid calls for her to resign or be dumped from her portfolio by the Prime Minister.

The extended absence means she will miss the next fortnight of parliamentary sittings in Canberra, as well as the forensic scrutiny and interrogation often experienced during Senate estimates hearings.

Senator Reynolds was admitted to hospital almost a fortnight ago to receive treatment for a pre-existing heart condition, after a fortnight of sustained criticism of her handling of a rape allegation by a former staff member.

More to come.
