Mr TAYLOR (Hume) (14:27): My question is to the Prime Minister. I refer to the Prime Minister's and the Treasurer's repeated refusals to rule out changes to negative gearing. Will the Prime Minister give a commitment to the Australian people that Labor's changes will include grandfathering of pre-existing negative gearing arrangements? Mr Jones interjecting— The SPEAKER: Order! The Assistant Treasurer will cease interjecting. Mr Rick Wilson interjecting— The SPEAKER: Order! The member for O'Connor will cease interjecting. Honourable members interjecting— The SPEAKER: Order! Members on my left and my right: I've been crystal clear during the week. The time for interjecting is not before I call a minister or prime minister. The Prime Minister has the call.
