Deep rifts widen further within Coalition under climate change pressure

Liberal senator Jonathan Duniam has warned the Coalition will face a "mass exodus" from its frontbench if it adopts a net zero policy without caveats, handing Opposition leader Sussan Ley a fresh test over the party's stance on climate action. The warning comes a day after Liberal MP Andrew Hastie threatened to quit the party if it pursued a policy of net zero emissions by 2050.
