Senator BOB BROWN (Tasmania—Leader of the Australian Greens) (14:24): Mr President, I have a further supplementary question to follow up on the Public Interest Advocacy Centre's revelation. I ask the minister: will he hold an independent inquiry into what is clearly a cover-up by Prime Minister Howard and Defence Minister Hill at the time of Australia's role in events at Abu Ghraib which put at great danger our troops in Iraq and allied troops in Iraq?
