PIC AND PUB PLS Kevin Rudd told 'put up or shut up' as Australia power struggle with Julia Gillard erupts The Australian newspaper reported that in the 103-member Labor caucus, Mrs Gillard currently had the support of 51 MPs while 31 were behind mr Rudd with 21 undecided. In a separate interview with Sky News, Mr Crean said the dispute was "starving Labor of oxygen." "This has got to end," he said. Mr Rudd, who is in Mexico for the G20 meeting, told reporters he was "disappointed" by Mr Crean's remarks and attempted to downplay the simmering tensions. Asked whether he would challenge Mrs Gillard, who is now badly lagging in polls, he said: "That is not in prospect, because we have a prime minister and I am the foreign minister." Mrs Gillard herself was asked repeatedly during a press conference whether she would discipline or sack Mr Rudd for disloyalty, but refused to give a direct answer. She also dodged questions on whether she would call a leadership ballot. "My focus is on doing what I need to do today as prime minister, to set us up to be the nation we want to be in the future," she said. As prime minister, I'll continue to show my characteristic determination to get the job done. She continued: "I'm getting on with the job with the strong support of my caucus colleagues. I'm getting on with my job. Kevin Rudd's getting on with his. Party insiders were cited by the media as saying a leadership ballot could come as early as next Monday, when parliament sits again. Yesterday Mr Rudd was forced to insist he was a changed man after a footage showing him in an expletive-filled rant about a Chinese interpreter was leaked on to YouTube. The two-minute video, uploaded onto the website by a user calling themselves "HappyVegemiteKR," shows an irate Mr Rudd trying to record a message in Mandarin and railing against the interpreter who wrote the text. Mrs Gillard's office denied leaking the footage.
