Libor scandal: Marcus Agius to face investors as Jerry Del Missier takes to the stand with MPs Barclays" chairman and deputy chairman will travel to shareholders and investors groups to explain their strategy for stemming the crisis that has ripped through the bank and its boardroom. The pair are expected to use the meetings to sound out investors on the plan to elevate Sir Mike to chairman so he can swiftly start looking for a new chief executive and fill the management vacuum at the top of the bank. But it comes as Mr Del Missier, Barclays former chief operating officer - accused of ordering his subordinates to rig the bank's Libor submission in 2008 - goes before the Treasury Select Committee. The committee, which will also question directors of the Financial Services Authority today, is likely to quiz Mr Del Missier on how the mistake was made and why he failed to check the instruction, given he knew it broke the rules. The session, set for this afternoon, has been eagerly anticipated as a chance for Mr Del Missier to blow the lid on the culture of Barclays under Mr Diamond. Sources at Barclays insist the former star executive has not been prepared for hearing by the bank. In the memo he admitted that customers, shareholders and regulators "all have a right to feel let down" by the bank after it admitted to manipulating Libor and was fined £290m to settle with regulators. But Mr Agius, insisted that other banks could face a bigger fall-out. "As other banks settle with authorities, and their details become public, and various governments" inquiries shed more light, our situation will eventually be put in perspective," he said. The Treasury is working on plans to make financial recklessness a criminal offensive under a new "Fred's Law." Separately the US Justice Department has reportedly started building criminal cases against several institutions and their employees relating to the manipulation of Libor.
