Australian PM Malcolm Turnbull under leadership threat - analysis

Labor also opened up its advantage over the coalition, now leading 55 percent to 45 percent on a two-party preferred basis. Malcolm Turnbull's personal approval also took a battering, falling from 57 to 48 percent. RNZ journalist and presenter Alex Perrottet keeps his finger on the pulse of Australian politics.
