RBS may face full-year losses of up to £8bn, after the bank said it needed another £3.1bn for claims relating to the financial crisis.
Baroness Wheatcroft, former editor-in-chief of the Wall Street Journal, told the Today programme that the bank's current losses "could get worse".
Asked about the possibility of the bank granting its senior employees 200% bonuses, Baroness Wheatcroft added that RBS would be a "better bank" without its bonus culture.
