Australian deputy PM resigns

Australia's deputy prime minister yesterday said he will resign as leader of his party after weeks of pressure over an affair with a staffer that brought him into open conflict with his premier and a new allegation of sexual harassment emerged.

Barnaby Joyce said he will step down on Monday as leader of the National party, the junior partner in Prime Minister Malcolm Turnbull's centre-right coalition, after resisting earlier calls to quit over the affair with his former media secretary, with whom he is expecting a child.

He will remain in parliament, safeguarding Turnbull's shaky one-seat majority. The National Party will now elect a new leader, who will also become deputy prime minister under the terms of the coalition agreement with Turnbull's Liberal party.

Joyce's decision came after a falling-out with Turnbull, who is in the United States for meetings with President Donald Trump and who declined to leave him in charge while he is out of the country.

Turnbull called Joyce's affair a "shocking error of judgment" last week, to which Joyce responded by calling Turnbull "inept".

Joyce denied any wrongdoing but acknowledged the allegation had hastened his decision.
