By Steve Slater LONDON (Reuters) - Barclays promised a rigorous review of executive pay on Thursday, as shareholders at the bank's annual meeting said they remain unconvinced that big bonus payouts will be abandoned by its new bosses as part of a new ethical drive. Chief Executive Antony Jenkins, drafted in last year to tear up Barclays' profits-at-all-costs culture, told shareholders it would take time for them to see the benefits of his multi-billion-pound overhaul.

British bank Barclays, seeking to recover from last year's damaging Libor rate-rigging scandal, announced on Wednesday that it bounced back into net profits in the first quarter of 2013. Earnings after taxation stood at £839 million ($1.28 billion, 983 million euros) in the three months to March 31, Barclays said in a results statement. That contrasted with a net loss of £598 million in the same part of 2012.

By Steve Slater LONDON (Reuters) - Investment banking made most of the first quarter profit at British bank Barclays, highlighting the challenge for the lender's new boss in making money as he shrinks that part of the business. Chief Executive Antony Jenkins was brought in to bring a more ethical approach to Britain's third largest bank after scandals over rate-fixing and big bonuses in the investment banking arm that was built up by his predecessor Bob Diamond.

By Steve Slater LONDON (Reuters) - Rich Ricci, the boss of Barclays' investment bank who collected $26 million (17 million pounds) in deferred bonuses last month, is leaving the scandal-hit bank as its new chief executive seeks to cut back executive pay and repair its image. The American-born Ricci, a star performer at Barclays known for his love of horse racing, was a key lieutenant of Bob Diamond, the former chief executive who left Britain's third largest bank last year after a Libor interest rate rigging scandal.
