Marcus Agius, chairman for 5-1/2 years

Marcus Agius, chairman for 5-1/2 years, oakley sunglasses outlet will step down once a replacement is found. Barclays is also searching for a chief executive. Bob Diamond, who was CEO from the start of 2011, quit with immediate effect a week after the Libor settlement, following a political and public backlash. When he left, Agius took on the top executive responsibilities. The fallout from the scandal is expected to overshadow the bank's half-year results on Friday, which should show it made an underlying profit of 3.8 billion pounds ($5.94 billion), according to the average estimate of analysts polled by the bank. Rich Ricci, head of Barclays' investment banks, is not interested in being chief executive, a person familiar with him said. He was not seen oakley lifestyle sunglasses as a likely replacement for Diamond anyway, as he had been his key lieutenant for many years. Barclays is expected to look for external candidates to fill both roles. Headhunter Spencer Stuart is helping Agius in the search for a CEO and Ana Mann's MW is helping John Sunderland, a non-executive director at the bank, run the chairman search. CEO candidates include former Barclays finance director and a current advisor Naguib Kheraj; Antony Jenkins, head of its retail business; and Bill Winters, oakley limited editions sunglasses former co-head of J.P.Morgan's investment bank.
