Senator BILYK (Tasmania) (14:24): Mr President, I ask a supplementary question. If there is overwhelming support for Prime Minister Turnbull's energy policy, as claimed by the Prime Minister last Tuesday and by Minister Pyne this morning, why has the Prime Minister today dumped his National Energy Guarantee? Honourable senators interjecting— The PRESIDENT: Order! I asked for silence during questions. These are matters for debate. There is an opportunity after question time for debate. Senator Payne.
