My question is to the Prime Minister. Just in question time today, the Prime Minister and the Treasurer have said that the cost of the government's 10-year corporate tax cut is $26 billion, $36½ billion, then $35.6 billion, then $65.4 billion, and in their latest answer it was back at $35 billion. Prime Minister, how much will the 10-year figure cost taxpayers at the next election?
