Mr President, I ask a supplementary question. Today I got a letter from the Prime Minister declining my invitation that he give evidence to the Senate committee inquiring into this matter. He declined on the basis that this parliamentary question time is the appropriate forum for him and you, Minister, to answer questions of this nature. Why was the environment committee told at budget estimates that 19 roofs of a small sample of roofs were found live when the real number is clearly much higher? Minister, do as promised by the Prime Minister: face up, fess up—what is the real number?
