Ms CATHERINE KING (Ballarat) (14:10): My question is to the Prime Minister. A short time ago, Simon Birmingham told Senate estimates the Prime Minister's chief of staff has briefed the Prime Minister on his findings about whether the Prime Minister's office briefed against Brittany Higgins's loved ones. Can the Prime Minister now finally tell us: did his office seek to undermine Brittany Higgins's loved ones? The SPEAKER: Before I give the Prime Minister the call, just a caution now for future questions. Members need to be referred to by their correct titles and so do senators. An opposition member interjecting— The SPEAKER: I just follow the rules.
