JP Morgan parts with the London Whale The WSJ reports that Bruno Iksil, nicknamed the London Whale because of his market-moving trades, is not listed in an employee database as of July 12. They claims that his direct boss, Javier Martin-Artajo, and his manager, Achilles Macris, have also been removed. Last month he told Congress it would claw back millions of dollars in bonuses from executives involved the loss that originated from the bank's London office. The bank stunned Wall Street when it disclosed that a series of bets made by the CIO on the health of major companies had triggered the multi-billion dollar loss.
