On January 14, the UK government announced proposals that would give the UK Financial Services Authority (FSA) new statutory powers. Under the proposals, the FSA would be categorized as a "specified prosecutor" under the UK Serious Organised Crime and Police Act 2005 and would be given power to grant immunity when it investigates criminal cases such as insider dealing. The proposed change is to be made by a provision in the Coroners and Justice Bill.
