The Former City Minister Lord Myners has said that he is "not aware" of anyone at Whitehall putting pressure on the Bank of England to encourage banks to set Libor rates.
A memo disclosed by Barclays last night documenting a phone conversation with Paul Tucker, the deputy governor of the Bank of England, suggested he had hinted that senior Whitehall figures were pushing for this.
Speaking on the BBC's Today programme, he said: "I can say quite categorically that I didn't speak to Paul Tucker or anybody at the Bank of England about the Libor rate-setting process."
He also appeared to take a swipe at the Labour Former Business Minister Baroness Vadera who said last night that she had "no recollection" of speaking to anyone at the Bank of England about rate rigging.
Lord Myners said "I'm not falling into the class of people that have no recollection". Listen to the interview here.
Bob Diamond tonight angrily rejected suggestions that he misled MPs over regulators' concerns about activities at Barclays.
The Bank of England's Paul Tucker told MPs he refuted claims that he attempted to influence Barclays into manipulating the Libor rate.
MPs will be hoping the Deputy Governor of the Bank of England will shed some light on unanswered questions about rate-fixing at Barclays.
