'No excuses' for Gillard: Crean Prime Minister Julia Gillard is expected to unveil her new Cabinet on Monday. SACKED Labor minister Simon Crean says Julia Gillard will have no excuses for not running a tight ship after the prime minister reshuffles her ministry. Ministers Gary Gray and Jason Clare are expected to be elevated to cabinet when Ms Gillard announces her sixth reshuffle since the 2010 election on Monday. Mr Gray, who hails from resource-rich Western Australia, is widely expected to take on the mining portfolio, after Martin Ferguson moved to the backbench on Friday. Mr Ferguson joined Kim Carr and Chris Bowen in resigning after their role in trying to resurrect Kevin Rudd's leadership. Mr Crean, who was sacked over his part in the leadership tilt, told Macquarie Radio Ms Gillard would have no excuses for not improving government and cabinet processes. "She can't blame the potential for leaking, now that she's got a cabinet that she put in," he said. As pressure mounted on ministers Anthony Albanese and Mark Butler, who previously have come out in support of Mr Rudd, Mr Crean said there was no need to sack any more Rudd backers. "It's over and we have to move forward," he said, adding Ms Gillard would have "a fresh team." Labor frontbencher Greg Combet said the new team needed to shift from talking about internal matters to taking on Opposition Leader Tony Abbott. "All of my colleagues need to think about that - the people we are arguing with are on the other side of the chamber," he told ABC radio. Mr Combet said the events of last week were a fiasco. "I was just astonished at what was taking place," he said. Deputy opposition leader Julie Bishop said Mr Gray, whose WA seat will host community cabinet on Wednesday, had been a champion of temporary skilled migration visas because they were essential to major mining projects. "Given that the prime minister has declared a war on overseas skilled migrants, it will be interesting to see how effective Gary Gray can be in combating her destructive and damaging comments," she told Sky News. Ms Bishop said keeping Mr Albanese was "farcical." Labor backbencher Andrew Leigh, also tipped for promotion, defended Mr Albanese as a stalwart of the party who was passionate about his portfolio and good policy. Ms Gillard has the job of filling the portfolios of tertiary education, science, skills, resources and energy, arts, human services, small business, regional development, local government and parliamentary secretary for foreign affairs. Other MPs and senators mentioned for promotion include Kate Ellis, David Bradbury, Catherine King, David Feeney, Sharon Bird and Jacinta Collins.
