Mr BUTLER (Port Adelaide) (14:49): The Prime Minister's former energy adviser Danny Price said that the Prime Minister's refusal to even consider an emissions intensity scheme: Shows a lack of spine … By doing this, it means they are the party of increasing electricity prices and reduced energy security. Will the Prime Minister confirm that his lack of spine and his failure to stand up to Senator Bernardi have made the Liberal government the party of increasing electricity prices and reduced energy security?
