Ms PLIBERSEK (Sydney) (14:53): My question is to the Prime Minister. Does the Prime Minister's model of a national anticorruption commission have the power to investigate the energy minister's use of forged documents to attack the Lord Mayor of Sydney? The SPEAKER: The Leader of the House has the call. Mr Dutton: Mr Speaker, the standing orders are very clear in relation to those sorts of baseless allegations, impugning a member of this House, and they are false allegations, unfounded, and it should be withdrawn. The SPEAKER: I am happy to hear from the Manager of Opposition Business. Mr Burke: Mr Speaker, it's been the case for quite some time that, if a minister wants to reject something within a question, they have the opportunity to do so in the answer. The question does not assert something as fact; it asks a question. The SPEAKER: The Manager of Opposition Business will resume his seat. Standing order 100(d)(iv) talks about imputations, and certainly there's an imputation in that question. I am happy to give the questioner the opportunity to reword the question. Ms PLIBERSEK: My question is to the Prime Minister. Does the Prime Minister's model of a national anticorruption commission have the power to investigate the use of forged documents to attack a lord mayor?
