In other news from Britain, police have confirmed a man found dead in a London park Tuesday was a potential witness in the Enron fraud case. The man, Neil Coulbeck, was a former employee of the Royal Bank of Scotland. He had been interviewed by the FBI about the role of Bank of Scotland subsidiary NatWest in selling off part of its Enron unit. His death comes as Britain is locked in an internal political struggle over the extradition of three NatWest bankers to the United States. The three are being extradited under a treaty critics say is one-sided because the US has yet to ratify it.
