David Drumm's absence from the trial was described as 'Hamlet without the Prince' by Pat Whelan's lawyers but the jury was never told why the former bank boss wasn't in the dock.
According to Sean FitzPatrick, David Drumm told him the deal to unwind Sean Quinn's 29% Contracts for Difference stake in the bank was 'kosher'. The former Anglo Chairman said Drumm told him he didn't need to know the names of the Maple Ten but assured him they were men of substance.
According to Pat Whelan, Drumm was almost in daily contact with the Financial Regulator about the Quinn unwind, so much so , he said it was like there was a hotline between them.
Sean FitzPatrick would later tell gardai that he did not have a social relationship with David Drumm, who succeeded him as Anglo CEO in 2005. He said the his advice was rarely sought because of Drumm's need to let the other executives in the bank know he was in charge.
Mr Drumm resigned as CEO of Anglo in December 2008, a day after Sean FitzPatrick quit as Chairman. He is currently living in the USA where he filed for bankruptcy in 2010 listing debts of €10.3 million.
Mr Drumm's bankruptcy case is being contested by his former employers (now IBRC) who allege he "fraudulently" tried to hide transfers of cash and assets. The case is due to be heard in a Boston court, over five days, late next month.
