Senator JOYCE (Queensland—Leader of The Nationals in the Senate) (14:50): Mr President, I ask a further supplementary question. I refer to the Prime Minister's infamous statement on 16 August last year: 'There will be no carbon tax under the government I lead.' Given the active undermining that is currently going on by people proximate to you, Senator Wong—in fact, all around you—and given that we might soon see a carbon tax in place, does that mean that Julia Gillard is now no longer going to lead the government? The PRESIDENT: Senator Wong, you need only answer that part of the question that refers to your portfolio.
