SIMEON BROWN: Well, thank you, Madam Chair, and thank you for the opportunity to continue with this line of questioning, which I think is actually very relevant and quite a detailed question. I know the Minister in the chair understands the nature of the question and is, I hope, going to be able to give a detailed answer to how that figure was come to. I make the point that this is the committee of the whole House—this is the only chance that this Parliament has to interrogate this piece of legislation.
