Ms PLIBERSEK (Sydney—Deputy Leader of the Opposition) (14:12): My question is to the Prime Minister. I refer to comments by Liberal Senator and former parliamentary secretary to the Prime Minister, Cory Bernardi, who said: 'Playing games with our scientists and research hasn't seemed to have done the government any favours.' Is the Prime Minister's backdown from the shameful attempt to hold 1700 scientists hostage all about the Prime Minister's leadership and nothing about the government? The SPEAKER: I call the Honourable Prime Minister, but he will ignore the last part of the question. Opposition members interjecting— The SPEAKER: The members for Grayndler and Jagajaga will desist.
