Ms PLIBERSEK (Sydney—Deputy Leader of the Opposition) (14:53): My question is to the Prime Minister. On 9 September last year, when asked to name his greatest achievement since deposing the former Prime Minister, the member for Warringah, the current Prime Minister said, 'reforms to business tax'. Is the Prime Minister still committed to his centrepiece $50 billion tax cut for big business in full? If not, what will the Prime Minister's new greatest achievement be?
