Mr Speaker, my question is to the Prime Minister. I refer the Prime Minister to the Deloitte WA share index, underpinned by Western Australian mining companies, which fell 12.6 per cent in May, significantly more than any other major international share index. Does the Prime Minister accept that he was wrong when he claimed the supertax on mining had no impact on the share values of mining companies and on the retirement incomes of millions of Australians?
