Markus Agios, in a testimony to the Crown Court of Southwark, said that he had seen a document describing the fees approved for Qatari investors at the British bank for the first time "four years after approval of these payments", despite the large and sensitive position he took at that time.
"He does not know how the 280 million pounds ($ 365 million) of extra fees were negotiated, or how that figure was reached in October 2008 at the height of the financial crisis," said the banker.
"Not only did I not see the document, I was not even aware of its existence," he said, noting that "the first time he saw the document was in 2012."
John Farley, former chief executive of Barclays and some of his former senior counterparts, Roger Jenkins, Tom Calaris and Richard Booth, are facing charges for fraud through false representation in side deals with Doha.
Qatari investors are pumping nearly $ 4 billion in Barclays during two fundraising operations at the height of the 2008 credit crisis, and thanks to bank financing, the government has been able to prevent government bailouts.
Four of Barclays' former executives deceived shareholders, the market and other investors by not revealing that Barclays paid more than £ 322 million to Qatar through two advisory services more than 10 years ago, according to the Serious Fraud Office in Britain. Years that deny defendants.
According to documents submitted to the Court, Farley and Agios jointly obtained full authority to organize a second round of fundraising after a meeting of a Board Finance Committee, set up by Barclays on October 28, 2008, that "fair and reasonable" fees contained, according to documents.
