Here's a report by Christian Aid that claims that billions of dollars of oil money that has already been transferred to the US-controlled Coalition Provisional Authority (CPA) has effectively disappeared into a financial black hole.
For all the talk of freedom and democracy for the Iraqi people before, during and after the war which toppled Saddam Hussein there is no way of knowing how the vast majority of this money has been spent.
No surprise. Call in some auditors! (but not Arthur "Shred'em" Andersons please).
