Expect bloodbath in the Gillard cabinet following the leadership challenge dare made by senior Labor Minister Simon Crean. Reports said that Australian Labor Party (ALP) leader and Prime Minister Julia Gillard will announce on Monday a cabinet revamp following recent developments in the party.

Although Ms Gillard has refused to comment on the speculations, if the cabinet reshuffle would push through, it would be the sixth in her almost three years term.

A cabinet revamp is apparently inevitable after Ms Gillard had sacked Mr Crean, while Ministers Chris Bowen, Martin Ferguson and Kim Carr had resigned, while Parliamentary Secretary Richard Marles, chief whip Joel Fitzgibbons and whips Ed Husic and Janelle Saffin also quit their respective posts.

However, The Australian reported that one supporter of former Prime Minister Kevin Rudd - who backed out of the ALP leadership ballot - Leader of the House Anthony Albanese will not be removed from his position but even be promoted by adding to his responsibilities the Regional Development portfolio of Mr Crean.

The daily said also expected to move up the ranks are Gary Gray as Resources and Energy Minister, and some upward movements for Home Affairs Minister Jason Clare, Employment and Childcare Minister Kate Ellis, Assistant Treasurer David Bradbury, Sports Minister Kate Lundy and Parliamentary Secretary Don Farrell.

Reports also said that Ms Gillard plans to reduce the number of cabinet positions to 21.

Mr Albanese has been criticised for not resigning together with other Rudd supporters, but Mr Albanese said he enjoys the confidence of the PM and kept his world not to back a leadership spill versus a sitting prime minister.

Meanwhile, senior minister Greg Combet sought a stop for backstabbing in the ALP following last week's leadership challenge.

"We've experienced deliberate destabilization for a long period of time now and when it all came to a head on the Thursday, Kevin Rudd didn't front up and that must now be an end to it ... We've got a lot of really talented people in the Labor caucus and I think you'll find we've got a capable group of people who step into the available positions," ABC quote Mr Combet.

Mr Crean said on Monday that the PM cannot blame the potential for leaking because of the reports of the cabinet shake-up.

He also disclosed that Mr Rudd actually sent him an SMS to delay any leadership moves but he only saw it after me had called for a press conference that called for the spill.

Mt Crean said the former PM must stop covering himself and even urged him to run against Ms Gillard 10 minutes before the caucus. "Him not running was never part of the discussions we had," Mr Crean disclosed.
