The chair of parliaments Public Accounts Committee says the former chief of HSBC must face serious questions after once-secret papers outlined how the bank helped the wealthy dodge taxes. Margaret Hodge told the BBC on Monday, Feb. 9, 2015 that Stephen Green, HSBC’s former CEO, was either “asleep at the wheel, or he did know and he was therefore involved in dodgy tax practices.” (AP Photo/Kirsty Wigglesworth, File)
