FILE - In this Friday, Feb. 24, 2012 file photo, former Australian Prime Minister Kevin Rudd speaks during a press conference after his arrival at Brisbane airport, Australia. Speculation is intensifying that Prime Minister Julia Gillard will soon face a leadership challenge in the face of opinion polls that suggest her government is headed for a crushing defeat at elections this year. Center-left Labor Party government lawmakers on Wednesday, March 29, 2013 publically stood by their beleaguered leader. But The Australian Financial Review newspaper reported three unnamed senior Gillard backers saying support among government ranks for her predecessor Rudd was growing. (AP Photo/Tertius Pickard, File)
