Labour are calling for George Osborne to prevent the Royal Back of Scotland giving bumper bonuses worth more than salary levels to senior staff members.
Royal Bank of Scotland, 81% owned by the taxpayer, is expected to invoke a clause in the new EU rules on bankers bonuses whereby any bonus worth twice the level of annual salary can only be awarded with shareholder approval, The Financial Times reports.
As Chancellor, Mr Osborne is effectively the heavily lossmaking bank's main shareholder.
