Barclays: Rake ready to quit BT and easyJet to become chairman at Barclays While some have called for an external chairman to be appointed, there is a concern that the departure of Bob Diamond as chief executive, and Jerry del Missier, the chief operating officer, has left a vacuum at the top of Barclays. One investor said: "It's tempting to call for a clean sweep at the top of Barclays but it's prudent to be cautious and not demand change for change's sake," he said. Sir Mike is there and capable of steadying the ship. Yesterday Japan Bank for International Cooperation dropped Barclays from its list of managers in the launch of a US dollar five-year bond in what appeared to be the first time the bank has lost business since the fall-out from the Libor scandal. Barclays, which paid a £290m settlement with US and UK regulators as part of a global investigation into Libor fixing, faces fresh embarrassment on Monday as it was confirmed that Mr del Missier will give evidence to the Treasury Select Committee. According to Mr Diamond, it was Mr del Messier, his right-hand-man for 16 years, who gave instructions for traders to falsify Barclays" Libor submissions in 2008. Mr Diamond said Mr del Messier "misinterpreted" some "advice" from Paul Tucker about Barclays" funding costs as an instruction from the deputy Governor of the Bank of England for Barclays to lower its submissions. Mr Del Messier has remained silent while Mr Diamond, Mr Tucker, and Mr Agius have given evidence to MPs. There was dismay yesterday that Mr Del Messier is scheduled to give evidence to the MPs for only 45minutes. He will be followed by Lord Turner, chairman of the Financial Services Authority; and his colleagues, Andrew Bailey, head of bank supervision, and Tracey McDermott, head of crime and enforcement.
