Tue, 25 Feb 14

A former partner at Ernst & Young has told the BBC that suspicious rule changes made by Dubai’s mineral regulator led to key findings being covered up. He also claims that Ernst & Young downplayed the severity of the situation. The BBC’s Andrew Verity tells us more. And we hear how Wall Street has responded to a potential new tax on banks.
