Robert Peston on Barclays 'shocking behaviour'
The Financial Services Authority (FSA) has fined Barclays Bank a record £59.5m for attempting to manipulate the interest rates at which banks lend to each other.
Barclays chief executive Bob Diamond and three other of the banks' most senior executives will forgo their bonuses for this year.
Including the record FSA fine, Barclays has agreed to pay penalties totalling £290m to UK and US authorities.
The BBC's Business Editor, Robert Peston said, "It's quite hard to think of behaviour by a bank as shocking as this".
