BARCLAYS has named Sir David Walker as its new non-executive chairman. He is a senior banker who led the 2009 UK government inquiry into the rules governing how banks are run. Sir David replaces Marcus Agius, who resigned after BARCLAYS was fined for its part in the Libor-fixing scandal. He will earn £750,000 a year to work "no fewer than four days per week". Sir David is currently a senior advisor to Morgan Stanley, having previously been chairman of MORGAN STANLEY INTERNATIONAL. Before that, he was an executive director of the BANK OF ENGLAND and deputy chairman of LLOYDS BANK.
