Ms PLIBERSEK (Sydney—Deputy Leader of the Opposition) (14:31): My question is to the Prime Minister. I ask the Prime Minister: is the Prime Minister aware that the publisher of the former Prime Minister's book has said, 'I expect Tony to make the case for the Liberal Party to return to its conservative roots,' about his new book? Isn't it now clear that, no matter how many concessions the Prime Minister makes to the extreme Right of his party, it will always be followed by new policy demands? Why does the policy of this government always reflect the demands of the Liberal Party's extreme Right? The SPEAKER: Before I call the Prime Minister, I inform the House that I clearly ruled the previous question out of order. The final part of the member for Sydney's question is just in order, but I caution those asking questions that I will in future rule out of order questions that are a substantial proportion out of order just with a tag at the end. I call the Prime Minister.
