Senator CORMANN (Western Australia—Minister for Finance and the Public Service, Vice-President of the Executive Council and Leader of the Government in the Senate) (14:18): As I've indicated to the chamber on a number of occasions now, the reason Mr Turnbull is no longer Prime Minister is that he lost the confidence of a majority of members in the Liberal Party party room. The Liberal Party party room elected Mr Morrison and Mr Frydenberg as our leader and deputy leader. It is very clearly understood that, under our Westminster system of parliamentary democracy, prime ministers need to both enjoy victory at the election and continue to enjoy majority support in their respective party room—something I know that the Labor Party understands very well, because I know Mr Shorten has been involved directly in changing prime ministers on the Labor Party's side on two occasions. I don't think that Mr Shorten has any difficulty understanding what happened, because he has been directly involved on two occasions. The PRESIDENT: Senator Urquhart, a supplementary question.
