Here is a timeline of events from his joining the bank to his leaving it:
More From This Section
1996 - Bob Diamond is appointed Chief Executive of Barclays Global Markets.
1997 - In a strategic U-turn, Barclays decides to dismantle its Barclays de Zoete Wedd (BZW) unit, which failed to fulfil the bank's ambition to make it a top global investment bank and ran into derivatives losses as the emerging markets crisis began.
- Credit Suisse First Boston buys BZW's equities business. Barclays is left with the rump investment banking unit, which it renamed Barclays Capital.
2002 - Diamond becomes executive director for markets.
2005 - Documents from the Financial Services Authority (FSA) and the U.S.'s Commodities Futures Trading Regulator (CFTC) will later detail multiple occasions when Barclays traders sought to manipulate the London Interbank Offer Rate (Libor) between 2005 and 2009 while Diamond headed the British bank's investment banking operations.
2007 - Barclays is trumped in October by a consortium led by Royal Bank of Scotland
2008 - Barclays refuses aid from the British government during the financial crisis and sells shares to Abu Dhabi and Qatar instead. Qatar's sovereign wealth fund pays 1.4 billion pounds in June for a 6.2 percent stake, and a member of Qatar's ruling family spent 432 million pounds on a 1.9 percent stake.
- Barclays Capital says in September it has relaunched its U.S. Equity Trading and Research division, following the acquisition for $1.75 billion of the North American investment banking and capital markets businesses of the bankrupt Lehman Brothers.
2009 - Diamond's pay slumps to 250,000 pounds in 2008 from over 21 million pounds in 2007. He did, however, receive 7.4 million pounds in cash and 22 million pounds' worth of shares awarded in previous years.
- Barclays completes the sale of its asset management arm to U.S. fund manager BlackRock in December for $15.2 billion, or $1.7 billion more than when it struck the deal in June after a jump in BlackRock's share price.
- Under the deal Barclays takes a 19.9 percent stake in the enlarged BlackRock Inc, the world's largest money manager. Barclays CEO John Varley and Barclays Capital CEO Bob Diamond both join the BlackRock board.
2011 - Bob Diamond takes over as chief executive on January 1, three months earlier than planned. Diamond takes over from John Varley, who is stepping down after six years as CEO.
- Diamond was paid a bonus of 6.5 million pounds for 2010 when he was head of Barclays Capital.
2012 - The British government orders an independent review into the workings of key lending rates between banks after Barclays is found guilty of manipulating them and fined $453 million.
- Barclays Chairman Marcus Agius resigns on July 2.
- Bob Diamond resigns on July 3 and will appear before the parliamentary committee probing the scandal on July 4.
