David Bermingham, Gary Mulgrew and Giles Darby are accused of advising NatWest to sell part
Opposition and business leaders have criticised the attorney general's decision to refuse a UK trial for three British bankers wanted in the US, BBC reported.
Lord Goldsmith said he saw no basis for the Serious Fraud Office to change its decision to leave the case with the US.
Shadow home secretary David Davis added that it showed extradition laws between the US and the UK were "one-sided".
Richard Lambert, director general of the CBI, said there was "terrific anger and terrific concern" about the decision.
