Mr SHORTEN (Maribyrnong—Leader of the Opposition) (14:26): My question is to the Prime Minister. Can the Prime Minister confirm that he will sack any cabinet minister who crosses the floor and votes in favour of marriage equality? Government members interjecting — Mr Mitchell: Mr Speaker, I rise on a point of order. I ask that you ask the Treasurer to withdraw the term that he used then. Mr Hockey: Hypocrite? Mr Mitchell: Exactly right—it has been ruled out before, you can ask your friends behind you. It has been ruled out as unparliamentary in this term of parliament. The SPEAKER: I ask the Treasurer, in the interests of the House, to withdraw. Mr Hockey: I withdraw 'hypocrite'. The SPEAKER: The Treasurer will withdraw in an unqualified way. Mr Hockey: I withdraw. Ms Butler interjecting — The SPEAKER: I do not need advice in the form of an interjection from probably the biggest interjector yesterday. I remind all members to withdraw without reservation. Ms O'Neil: Mr Speaker, I rise on a point of order. The SPEAKER: No, I am not taking a point of order; I am calling the Prime Minister.
