Senator CORMANN (Western Australia) (14:41): My question is to the minister representing the Treasurer, Senator Wong. With your indulgence, Mr President, before asking the question, may I join in congratulating Senator Wong on her elevation to the position of deputy leader of the government in the Senate. It is a great personal achievement indeed. Given the Gillard government predicted that its minerals resource rent tax would raise $4 billion this financial year when the Prime Minister and the Treasurer first signed the MRRT heads of agreement, followed by a prediction in the most recent budget that it would raise $3 billion this financial year which in turn was followed by a prediction in the most recent Mid-Year Economic and Fiscal Outlook that the MRRT would raise just $2 billion this financial year, can the minister confirm how much the MRRT has actually raised this financial year so far?
