I thank the honourable member for his question. Leader of the Opposition: in the four years that I was leader of the Australian Labor Party, I faced John Howard, I faced Brendan Nelson, I faced someone by the name of Malcolm Turnbull, and most recently, as the honourable member for Wentworth will recall, I faced Tony Abbott. I had four leaders in four years. These are matters for internal party deliberations in his party and in ours. Let us get onto questions about the country's future.
