Parmalat founder Calisto Tanzi is serving an eight-year sentence on marketrigging related to the stunning 2003 collapse of his dairy empire despite his advanced age.
But after the financial crisis they were brought in to fix RBS's investment bank, and the concern is that they did not get to grips with the marketrigging that continued on their watch.
They include stiffer penalties managers guilty of market-rigging are now more likely to go to jail and the power to offer plea-bargains to whistle-blowers.
Sources in the last Labour government have told me that it was well known at the time that ministers wanted to do everything possible to reduce the cost of credit to help get the economy moving, but have stressed that this was totally different from allegations about the rigging of the market and lying about the Libor rate.
