Australia prime minister 'inept'

Says deputy PM as sex scandal opens rift in coalition

Australia's parliamentary sex scandal opened a rift in the governing coalition yesterday as deputy leader Barnaby Joyce described Prime Minister Malcolm Turnbull as "inept" for criticising his affair with an aide.

Joyce, 50, whose National Party rules alongside Turnbull's Liberals, admitted last week to having an affair with his 33-year-old media adviser, who is pregnant with their child.

Turnbull on Thursday harshly admonished Joyce for making a "shocking error of judgement" for the affair and said he had created a "world of woe" for his wife, four daughters and lover Vikki Campion.

Turnbull, head of the Liberal Party, acknowledged that he was powerless to remove Joyce, who holds the deputy position as leader of smaller National Party on which he relies to govern.

He instead announced that a formal ban on sexual relations between cabinet members and their staff would be added to the ministerial code of conduct.

Joyce hit back in a defiant press conference in Canberra yesterday, refusing to resign and accusing Turnbull of interfering with internal National Party affairs. He blasted the PM's comments as "inept", "unnecessary" and causing "further harm".

"I don't believe people should be resigning in any job over personal issues," Joyce added.

He also batted away revelations he accepted a rent-free apartment from a millionaire after his marriage collapsed, saying the accommodation was just a gesture of support from a friend.

Daily media headlines about the affair have riveted the public and sparked debate about workplace culture in Australia amid the global #MeToo movement against sexual harassment.
