Barclays Plc
"The external pressure placed on Barclays has reached a level that risks damaging the franchise - I cannot let that happen," Diamond said in a statement six days after Britain's third-largest bank was fined nearly half a billion dollars for its part in manipulating a global benchmark interest rate.
Diamond's resignation was effective immediately. Outgoing chairman Marcus Agius will lead the search for a new CEO, despite having announced his own imminent departure a day earlier, declaring that "the buck stops with me".
Despite sending a long letter to staff on Monday that showed his resolve to continue, Diamond decided to quit later that day after Prime Minister David Cameron and finance minister George Osborne announced a parliamentary inquiry into the scandal, a person familiar with the matter said.

"The chairman of Barclays phoned me last night to let me know that this was the decision of the board and of Mr Diamond, and I think Mr Diamond made the right decision," Osborne said.
The resignation was "a first step towards that change of culture, that new age of responsibility we need to see", Osborne told BBC radio.
Newly appointed Chief Operating Officer Jerry del Missier, who has for years been a Diamond lieutenant, was also likely to quit, a source familiar with the situation said.
Barclays has admitted it submitted artificially low estimates of its borrowing costs to calculate interbank rates from late 2007 to May 2009. Large banks' estimates of how much interest they have to pay to borrow from one another are used to calculate the London Interbank Offered Rate, or Libor, the basis for trillions of dollars in contracts around the globe.
Barclays says it submitted low figures because it thought rivals were doing the same and higher submissions would have made it appear to be in trouble.
Diamond will still appear on Wednesday before the parliamentary committee probing the scandal, with Agius appearing on Thursday. The inquiry will report by the end of the year and influence the government's financial sector reforms.
NAMES IN THE FRAME
Anthony Jenkins, currently chief executive of Barclays retail and business banking, is the most likely internal candidate to replace Diamond, said Oriel Securities analyst Mike Trippitt. However, the firm may choose to look outside for a new leader to turn the page on the scandal.
"Promoting an existing manager might not look like it is doing enough to tackle problems with aspects of the bank's culture which the LIBOR scandal has exposed," one top 25 Barclays investor said, asking not to be identified.
Other names in the frame include former JPMorgan
"I struggle to see many worthy candidates to replace him," said a top 40 investor. "You must remember that in contrast to RBS, Barclays is two-thirds an investment bank ... You couldn't put a dull, boring banker in charge of the beast because you do need someone with a strong investment banking heritage to take the helm."
Analysts were surprised that Agius, who will stay until a new chairman is found, would lead the executive search so shortly after Barclays appeared to have sacrificed him in order to keep Diamond, who led the investment banking arm at the time of the rate-rigging.
"The timing is surprising, given the robust response that Bob Diamond and Barclays appeared to be putting up over the last 24 hours," said Ian Gordon, an analyst at Investec.
Barclays shares, which rose on the news of the departure of Agius on Monday, added another 2.3 percent in early trading in the current session, rising to 172.3 pence, outpacing a 0.7 percent rise in the European banking stocks index <.SX7P>. The shares were still down nearly 12 percent from Thursday's open.
Barclays was fined $453 million by U.S. and British authorities, the first bank to settle in an investigation that is looking at more than a dozen others, including Citigroup
Some analysts say Barclays has been unfairly punished for admitting practices that appear to have been rife across the world's big banks.
"In the short term, it has not been well served or rewarded for its co-operation with the regulators," said Investec's Ian Gordon in a note headed 'Mob rule'. "We expect Barclays' sharp share price underperformance to reverse as the market takes a more dispassionate look at the facts." (Writing by Will Waterman; Editing by Peter Graff)
