Barclays to search wide but replace Bob Diamond quickly Other internal replacements, include Naguib Kheraj, who is a senior adviser to the bank and its former finance director, and Tom Kalaris, a former investment banker and head of Barclays's wealth and investment management division. Outside Barclays, Bill Winters, the former co-chief executive of US investment bank JP Morgan and one of the architects of the Government's reform of the British banking system, is seen as a leading contender. The American-born investment banker is well-respected by politicians, regulators and crucially the Bank of England. His appointment would likely be welcomed by shareholders. Also in the running could be Richard Meddings, finance director of Standard Chartered. Mr Meddings helped draw up the plans for Britain's banking bail-out in 2008 and is highly-respected in the City, with extensive international experience.
