Labor seizes on 'war' in the coalition

Bill Shorten has hit out at a "war" between Malcolm Turnbull and his deputy Barnaby Joyce.

Mr Joyce on Friday criticised Mr Turnbull for his comments on his affair with a former staffer, labelling them harmful, inept and unnecessary.

"Quite frankly, the way these two men are behaving, neither of them are fit for the high office they currently hold," Mr Shorten told reporters in Melbourne, alongside his deputy Tanya Plibersek.
