Barclays executive Jerry del Missier quits over 'Libor lies' Mr del Missier was one of Mr Diamond's top two investment banking lieutenants and was recently moved to chief operating officer at the bank. Sources said that the move had been a surprise because Mr del Missier was a trader rather than operations man. His fellow co-head, Rich Ricci, was the operations expert. The sources suggested that Mr del Missier had been moved to make sure the investment bank was in the hands of someone who could clean up the operations rather than deliver trading profits. Mr del Missier said: "My 15 years at Barclays have been a time of great accomplishment, both for me personally and for the bank. I am grateful for the opportunities that were provided to me and proud of what we achieved. We built one of the premier global investment banks from scratch - something that we are all very proud of. The firm is as strong today as it ever has been and is incredibly well placed to succeed within the post financial reform competitive landscape. Chairman Marcus Agius said: "Jerry played a pivotal role in many of Barclays stand-out successes during the last 15 years, including his extraordinary contributions as part of the leadership team that built the investment bank. His many contributions to the firm were critical to why Barclays was able to weather the extreme market turbulence of the credit crisis as well as we did. His colleagues, clients and other stakeholders hold him in the highest regard.
