Hang on a second Ranga
Prime Minister Julia Gillard says it is not her fault that she may break an election promise and introduce a carbon tax while leader of the federal government.
Five days before the August 21 poll, Ms Gillard said there would be no carbon tax under the government she led.
Contudo, she has since vowed to set up a committee made up of MPs from all sides of politics to examine ways of pricing carbon.
Ms Gillard said because Labor now shared the balance of power in the lower house with the Australian Greens and independents, the circumstances around her original promise had changed.
