He did "enter a “supergrass” (informer) deal in the U.K." and ratted out everybody. After ratting out everybody (and avoiding extradition to the US), he withdrew from the plea deal and gambled that the UK jury would be sympathetic. On Oct. 9, as the SFO was finalizing its case against Hayes and his co-conspirators, a white envelope arrived. It was from Hayes’s lawyers. “As a matter of courtesy we are now in a position to advise that Mr. Hayes will plead Not Guilty to all Counts,” the letter said. “Accordingly he now formally withdraws from the process.” Having avoided extradition, the natural born trader was taking the biggest risk of his life, reneging on the deal and entrusting his fate to random jurors in a London courtroom.
