Senator McKENZIE (Victoria—Minister for Rural Health, Minister for Sport, Minister for Regional Communications and Deputy Leader of The Nationals) (14:11): Senator Gallacher—through you, Mr President—the coalition is made up of two separate parties. One is nearly 100 years old—the National Party, of which I'm deputy leader. And for the 45-odd years that the Liberal Party have been in existence—we don't vote on their leadership matters. We never have and we never will, because we're two separate parties, and that is how it should be. Opposition senators interjecting— The PRESIDENT: Order! Senator Jacinta Collins interjecting— The PRESIDENT: Senator Collins! If I call senators to order I expect them to be silent for at least a short period.
