Unlike the prior Labor government, this government works on the principle of ministerial responsibility. What that means is that every minister takes responsibility for every decision they make. In relation to Mr Brough, you know, Senator Cameron, because you have made much of this during question time and debate in this chamber this week, that there is currently a police investigation underway. Public denunciations do not prove guilt. No charges have been laid against Mr Brough. There is a police investigation underway, and I suggest we allow that investigation to take its course.
