Independent MP Tony Windsor has launched a furious attack on Opposition Leader Tony Abbott in Federal Parliament.

The Opposition again interrupted Question Time to accuse the Prime Minister of lying over the carbon tax and asking her to apologise to the Australian people.

But Mr Windsor said Mr Abbott would have been willing to introduce a carbon tax in order to win the support of independent MPs after the last election.

"This man, the Leader of the Opposition, was quite prepared to do that if he'd been given the nod on that particular day," Mr Windsor told Parliament.

"'I will do anything, anything to get this job' - they were the comments, and people know that, and they should know it.

"He made the point not only to me but to others in that negotiating period that he would do anything to get that job: 'I would do anything to get that job, Tony, the only thing I wouldn't do is sell my arse'."

Mr Windsor said Mr Abbott had been totally inconsistent on carbon pricing.

"You're an absolute disgrace in the way in which you're wandering around on this issue," he said.

"You have exactly the same target, you have the audacity to say you'll achieve that target through a much more expensive arrangement of putting a price on carbon."

Mr Abbott later said there were plenty of things he would not have done to become prime minister.

"I wasn't prepared to introduce a carbon tax in breach of my pre-election commitments," he said.

"There are lots of things I'd never do to get the top job, and one thing I'd never have done is break a pre-election promise."
