Two independent directors on the board that oversees HSBC’s British business may leave the bank over stricter rules aimed at holding bankers more accountable for reckless actions that may lead to the failure of a lender, according to a person with direct knowledge of the matter. Alan Thomson, a member of the audit and risk committees at HSBC Bank, has tendered his resignation and will leave the bank later this month, said the person, who was not authorized to discuss the matter publicly. John Trueman, deputy chairman of the bank’s British business, is also considering whether to leave over the new rules. [Dealbook]
