Former Victorian Labor Health Minister Jenny Mikakos has expressed her frustration and disappointment at not being properly briefed by Chief Health Officer Brett Sutton, as she supports calls for a royal commission into Premier Daniel Andrews and COVID-19.

Her bombshell came at a parliamentary inquiry into the scandal dubbed “slug-gate”, in which Professor Sutton’s conservative and powerful health orders have been called into question, amid claims a slug was planted by a health inspector following the death of an 86-year-old woman at Knox Private Hospital.
