NSW Premier Gladys Berejiklian will make a 'significant announcement' at 1pm today after it emerged she is being investigated by the state's corruption watchdog. She has reportedly told colleagues she will be resigning as premier. Liberal MP Peter Poulos told an Upper House inquiry: 'She's going to resign at one o'clock'. The watchdog known as ICAC is investigating whether Ms Berejiklian encouraged or allowed corrupt conduct by her secret ex-boyfriend and former MP Daryl Maguire between 2012 and 2018. It will also probe whether she breached public trust by not reporting any suspicion of corrupt conduct.
