Mr ABBOTT (Warringah—Leader of the Opposition) (14:34): Madam Speaker, I ask a supplementary question— Mr Albanese: Madam Speaker, a point of order: the member for Mackellar might like to withdraw. The SPEAKER: Member for Mackellar, withdraw. I may ask others to withdraw if they are not careful. Mrs Bronwyn Bishop: I withdraw. The SPEAKER: I thank the member. Mr ABBOTT: It is to the Prime Minister. How does the Prime Minister reconcile the answers she has just given with her pre-election pledge, 'There will be no carbon tax under the government I lead.'
