Top Barclays Banker Quits in Growing Scandal Morning Business Memo One of the world's most powerful banking executives has announced his immediate resignation. American executive Bob Diamond, 60, has quit as Barclays" CEO-the latest casualty of a financial markets scandal. Diamond caved in to growing pressure in Britain after the bank paid $453 million in fines. A joint US-UK investigation found that Barclays" traders had attempted to fix a key global interest rate benchmark.

Diamond "had been one of 18 co-hosts for a dinner in London later this month where guests are being asked to pay $25,000-$75,000 to raise money for Mr. Romney," says the FT.
