Kevin Rudd has confirmed he will stand against Prime Minister Julia Gillard in Monday’s Labor Party leadership ballot.
He would ”restore the trust” of the Australian people that she had lost, he told a news conference in Brisbane.
Ms Gillard, who ousted him as prime minister in June 2010, called the vote following weeks of speculation that he would challenge her for the top job. Speaking in Melbourne after Mr Rudd, she asked colleagues for support, stressing she was the right choice.
The ballot is to be conducted at 10:00 on Monday (23:00 GMT Sunday). It follows weeks of infighting over the leadership.
Mr Rudd resigned as foreign minister late on Tuesday, prompting Ms Gillard to call the leadership ballot a day later.
