PETER SLIPPER has yet to provide to the federal police the cabcharge receipts that he says show the taxi rort allegations levelled against him are a ''complete fabrication''.
''The AFP has not yet been provided information from MP Peter Slipper in relation to allegations of fraud relating to his use of cab charges (sic),'' an AFP spokeswoman said this afternoon.
The federal police are currently evaluating evidence against Mr Slipper regarding claims he misused Cabcharge dockets.
''As part of this evaluation process, AFP investigators are speaking to potential witnesses and gathering further information,'' a spokeswoman said.
At the end of the evaluation the AFP will announce whether the allegations are credible enough to launch a formal investigation, or whether they are without adequate legal foundation and will be ignored.
According to the Leader of the House of Representatives, Anthony Albanese, the receipts prove that the taxi rort allegations levelled against Mre Slipper are ''a fabrication''.
But the Opposition say that the Cabcharge documents are not enough to put him back in the Speaker's chair.
Mr Slipper has released a PDF document of 13 completed Cabcharge vouchers which, he says, clears him of allegations he handed over blank but signed vouchers to a driver earlier this year.
Mr Albanese said that by releasing the documents - already the subject of brewing controversy over their veracity and use Mr Slipper had effectively cleared himself of wrongdoing.
''Clearly [the dockets] show that the allegations that had been made, that he handed over blank Cabcharge dockets to a hire car driver on particular dates, are simply not correct,'' Mr Albanese said.
'' Certainly what that does is show that the criminal allegation is a fabrication. It's just not correct. When you're confronted by the facts, you have to determine that that is the case.
''...What's very clear is that Mr Slipper's statement at the time of the allegations, that they weren't true, that he always filled in his own Cabcharge dockets in accordance with entitlements and in accordance with what he was supposed to do, is correct.
Mr Albanese said that there was ''no impediment'' for Mr Slipper's return to the Speaker's chair ''if the criminal matters are dealt with.''
He confirmed the government would back Mr Slipper in the event a motion of no confidence was brought by an Independent or the Coalition.
But Tasmanian independent MP Andrew Wilkie remains set on blocking any such move until all allegations levelled against the Sunshine Coast MP are dealt with.
The Coalition is also continuing to insist that Mr Slipper does not return to the Speaker's job while he faces separate claims that he sexually harassed a staff member.
Mr Wilkie said that all the relevant inquiries - including claims of the sexual harassment of a male staffer - needed to be ''concluded'' before Mr Slipper considered a return to the position as he was subject to a ''higher standard'' than other member of Parliament.
''I am still firmly of the view that he should remain out of the Speaker's chair until all of the allegations against him have been dealt with,'' Mr Wilkie said.
''This isn't just any old member of the House of Representatives. Peter Slipper is the Speaker - he controls the parliament and he safeguards the standards of the parliament.''
''No man or woman should sit in that chair while there is any allegation against them.
''It's troubling that some in the government at least think he should resume the chair once the criminal matters (only) are dealt with.''
Independents Rob Oakeshott and Tony Windsor have also indicated they would consider voting with the Coalition to prevent Mr Slipper's return.
Mr Wilkie said he did not think it would come down to a vote against Mr Slipper, but added that if the Queensland MP did try and return while still under the cloud of sexual harassment allegations, there would likely be move against him.
Mr Wilkie also said that he would be prepared to move the motion, arguing that the Speaker "safeguards the standards of the Parliament".
Opposition Leader Tony Abbott said this morning that if Mr Slipper was in the Speaker's chair when Parliament resumes for the budget, it would be a sign that Prime Minister Julia Gillard did not take sexual harassment seriously.
The Opposition Leader said that it was his "strong instinct"that it was unlikely the embattled Speaker would try and return to the Speakership in May.
"Lets wait and see what he does," Mr Abbott said. "I would be very surprised if [Ms Gillard] tries to force the issue in the Parliament."
Greens Leader Christine Milne was not prepared to say whether the Greens MP Adam Bandt would support a motion of no confidence in the lower house.
Senator Milne said it was right that Mr Slipper had stood aside at the weekend, but stressed that he was entitled to the presumption of innocence.
"Trial by media is unhelfpul to the national debate and the Parliament," she said.
Mr Slipper is yet to respond in detail to the allegations that he sexually harassed his adviser, James Ashby, 33, earlier this year.
Yesterday, the Member for Fisher said that he will make a further statement in "due course".
"I repeat that I reject allegations that have been made against me," he said.
