'Immunity from prosecution' a major FSA weapon

It almost passed under the radar but, in light of the HBOS share drop of the other day, Alastair Darling - the UK Chancellor - announced on Thursday that anyone who snitches on their mates to the FSA about colleagues who try to manipulate share prices, will be immune from prosecution themselves.   This is seen as a powerful weapon for the FSA, as investment bankers have been reticent to say anything about such practices in the fear of getting caught out themselves. 

Now then, that Jeremy in the banking equities desk has been stopping me from getting a seven-figure bonus this year ... maybe I'll mention that to my new FSA mates down at Canary Wharf?
