Mr OAKESHOTT (Lyne) (14:24): Speaker, I ask a supplementary question—and, with the indulgence of the House, this can be answered at the end of question time as well. Does the Prime Minister also confirm for both major parties in the House today that there is a shared policy commitment to reach a five per cent reduction in carbon dioxide equivalents by 2020? The SPEAKER: Before I ask the Prime Minister to answer, she obviously cannot answer on behalf of anybody else. The Prime Minister has the call but can only answer in respect of her own party.
