David Bermingham, one of the so-called "NatWest Three" who were extradited to the United States on charges linked to fraud at Enron, has told MPs of the "catastrophic effect" the extradition had on him and his family.
He gave evidence to the Home Affairs Committee on 10 January 2012 as part of an inquiry into extradition policies.
Mr Bermingham, along with two other bankers, admitted conspiring with ex-Enron employees to defraud NatWest of $19m (£12m) and went to jail after a plea bargain.
Enron, once a successful energy firm, collapsed in 2001 with debts of $31.8bn (£18.3bn), becoming the second largest bankruptcy in the US.
He told MPs he was denied a proper hearing after being arrested in the UK and shipped off to jail in America.
He said that the previous government signed a treaty with the US that "let down" all UK citizens wanted by the American authorities.
