The Financial Times reports that the regulator is set to reverse its previous stance not to publish after coming under political pressure.
Andrew Tyrie, chairman of the Treasury Select Committee, yesterday wrote to Adair Turner, chairman of the FSA, to ask him to publish the full investigation.
The FT reports that chancellor George Osborne and business secretary Vince Cable have also pressurised the FSA to release the information.
Tyries says he understands that the FSA would now “seek permission from RBS to enable the release of more information from this investigation in the public interest.”
He adds that he understands the need for confidentiality in investigations but that RBS is a special case.
A leaked US embassy cable shows that RBS chairman Sir Phillip Hampton believes RBS directors breached their fiduciary duties during the financial crisis.
