Royal Bank of Scotland

Royal Bank of Scotland chairman Philip Hampton has defended the bonus due to be paid to chief executive Stephen Hester even though the British bank has been punished for rigging interest rates.

RBS, 82-percent owned by the taxpayer, has faced criticism over a deferred bonus of 780,000 pounds ($1.2 million) that Hester is set to receive in March. But Hampton told lawmakers on Monday that Hester's pay was modest by the industry's standards.
