 The divisions within the Coalition were laid bare in an episode of Four Corners, aired by the Australian Broadcasting Corporation on 9 November 2009. The program featured the Coalition's leader in the Senate, Nick Minchin, suggesting that man-made climate change was a conspiracy of the political left and disputing Turnbull's authority to strike a deal with the government on the ETS. Later in the month, Minchin spoke against the ETS in the Senate. Abbott — who had publicly supported the ETS — was now arguing that the Coalition should abandon the policy. Turnbull attacked Abbott's change of mind, stating: "Tony has expressed a number of views, each of which is at odds with the view he expressed before".
