The chairman of Lloyds Banking Group has admitted the company's manipulation of key interest rates was "truly shocking".
The company has been slapped with a £218m fine from US and UK regulators for manipulating the LIBOR inter-bank rate and the Repo Rate.
The Repo Rate was the benchmark used by the Bank of England to calculate how much banks paid to take part in the Government's Special Liquidity Scheme (SLS) to support banks during the financial crisis.
Lloyds chairman Lord Blackwell has replied to a highly critical letterwritten to him by the Bank of England's governor, Mark Carney.
"I absolutely share your concern about the nature of the SLS conduct, and in particular its implication for reducing fees," Lord Blackwell wrote.
"This was truly shocking conduct, undertaken when the Bank was on a lifeline of public support."
He also agreed that Lloyds would pay nearly £8m back to the Bank of England for fees it should have paid for the SLS.
