Four of Barclays’ top executives – including Bob Diamond and Rich Ricci – have pledged to give up their bonuses for this year after the UK bank accumulated more $450m of penalties for its role in the setting of Libor and its European equivalent.

The UK's Financial Services Authority today fined Barclays £59.5m, or $92.8m, following an investigation into misconduct relating to the setting of the Libor and Euro Interbank Offered Rate, or Euribor.
