Senator ABETZ (Tasmania—Leader of the Opposition in the Senate) (14:06): Mr President, I ask a further supplementary question. Is the minister aware of reports that his deputy, Senator Conroy, recently acknowledged that the Greens inspired carbon tax was destroying the government and admitted to grave reports about climate change science? Is this the real reason your deputy, Senator Conroy, was absent for Tuesday's vote on the carbon tax? Senator Conroy interjecting— The PRESIDENT: Senator Conroy, you need to withdraw. Senator Conroy: I withdraw, Mr President. The PRESIDENT: Thank you. Opposition senators interjecting— The PRESIDENT: When there is silence we will proceed. Senator Evans.
