PM's supporters say she's not moving Prime Minister Julia Gillard will not step down as Labor leader, frontbencher Stephen Conroy says. PRIME Minister Julia Gillard's top supporters say there's no way she'll step down this week and if there's to be any leadership showdown Kevin Rudd will have to challenge. The final week of the hung parliament kicks off on Monday, three years to the day since Ms Gillard took the top job from Mr Rudd and amid continued speculation he may be about to return the favour. The Labor leadership is back on the agenda after a string of bad poll results for Ms Gillard, with the latest Newspoll this week likely to add to her woes and further weaken her grip on power. But some of Ms Gillard's most senior backers were on Sunday dismissing any suggestion she would relinquish the job. "I don't believe she'll be stepping down," Communications Minister Stephen Conroy told Sky News. Senator Conroy said he still supported the prime minister and he believed the majority of caucus did too - including powerbroker Bill Shorten, a key figure in the toppling of Mr Rudd in 2010. Senator Conroy also joined his colleague Peter Garrett in declaring he would not serve on Mr Rudd's frontbench if he was reinstated. And the prime minister had made it "crystal clear" she would lead the government to the September election, he said. Nationals Leader Warren Truss guessed the chances of a Labor leadership change this week were about 50/50. Treasurer Wayne Swan was talking up the 43rd parliament's achievements on Sunday, pointing out that it has passed 582 pieces of legislation, with a big week of lawmaking still to come. The Senate and lower house will work overtime to nail down key bills on policies Labor wants to take to the September 14 election, including its schools funding reforms and the local government referendum.
