Former Labor MP Craig Thomson had illegally used up about $500,000 of Health Services Union (HSU) funds, according to the Fair Work Australia (FWA) report, which should be enough reason for him to cease from any active participation in the Parliament.

Opposition Leader Tony Abbott urged Mr Thomson On Tuesday to resign from the House of Representatives, stressing that he has embarrassed and disgraced his current position.

"I think that the best thing Craig Thomson could now do would be for him to leave parliament and let someone else represent the people of Dobell," Mr Abbott was reported as saying by The Australian in a radio interview.

The Labor Party, he added, should also reject votes that would come from Mr Thomson, who was recently eased out from the ruling caucus and presently sits in the Parliament as a crossbencher.

"Look, it is a disgrace, it is an embarrassment to the Labor Party which spawned and nurtured and protected this person and it's a disgrace to public morality that this has happened," the Liberal leader stressed.

"It really is unconscionable for the Labor Party and the Prime Minister to continue to rely on this person's vote," Mr Abbott said, adding that Prime Minister Julia Gillard should not hinge her survival on a tainted vote that would come from Mr Thomson, who must deal with a likely civil suit based on the FWA report that took more than three years to complete.

The Coalition headliner also called on independent MPs in the Parliament to rethink their support for the Gillard government, which anchors its existence on deals forged with MPs Tony Windsor and Rob Oakeshott.

However, Mr Windsor has declared today that he will continue backing Ms Gillard's rule with or without the FWA report, which he admitted he hasn't read.

"My arrangements with the government don't include Craig Thomson ... and I will be adhering to that agreement until I find good reason not to," the MP from New England told ABC Radio in an interview on Tuesday.

He also suggested that Mr Thomson cannot be just excluded from Parliamentary proceedings until he voluntary relieves himself of his legislative duties.

"The only way that would play out would be for Craig Thomson to leave the building," Mr Windsor explained.

Also, Australian Greens leader Christine Milne reminded the Coalition that amidst the legal entanglements that Mr Thomson now faces, the fact remains that he is an elected member of the Parliament.

"He is entitled to cast a vote in the parliament until he either resigns or he is not voted in at the next election, or obviously he is not pre-selected," Ms Milne told the Australian Associated Press (AAP) today.

Finance Minister Penny Wong added that the embattled MP must be given the chance to answer all the accusations trained against him, stressing that Mr Thomson is "entitled to defend himself."

But the senior Labor minister told ABC that the matter whether the suspended Labor MP should be allowed back into the party caucus could not be dealt with at this time.

"It's not a question to be answered now," Ms Wong insisted.
