Mr BOWEN (McMahon) (14:30): My question is to the Treasurer. The former Treasury Secretary, Ken Henry, recently said on the ABC's 7.30 that more than half of the budget deterioration is because of falling revenue. Does the Treasurer agree with Dr Henry's assessment? Ms Plibersek: Yes or no. The SPEAKER: I remind the member for Sydney she has been warned. Mr Bowen interjecting— The SPEAKER: The member for McMahon has asked his question. He will cease interjecting.
