""Senior managers at Barclays have warned staff in an internal memo that the Libor scandal will envelop other banks.

The memo circulated on Friday said that revelations about its rivals would "put in perspective" Barclays' culpability.....

.....According to the Barclays' memo to staff: "As other banks settle with authorities, and their details become public, and various governments' inquiries shed more light, our situation will eventually be put in perspective."

The memo, from Mr Agius and other senior executives, admitted that customers, shareholders and regulators "all have a right to feel let down" by the bank after it admitted to manipulating Libor, and incurred a £290m ($450m) fine from UK and US regulators.

Several banks are currently being investigated, both in the UK and the US, for allegedly manipulating Libor.

On Friday it emerged that the Federal Reserve Bank of New York - which is responsible for overseeing banks in the US city - discussed concerns about the way Libor was being set as early as May 2008.
