A row over bonuses has led to a hedge fund manager taking his former employer, Gulf International Bank, to a UK employment tribunal in a claim over unfair dismissal.

Sources close to the dispute, which is scheduled to be heard at a London tribunal next year, said Paul Firkins left Gulf in August 2002 after the bank turned down his request for a guaranteed bonus. Firkins, who worked at Gulf for more than three years, ran the Falcon Trend selection fund, an interest rate and currency futures hedge fund that he set up. The fund had generated an above-average 22% return in 2001, according to HedgeFund.Net, a data provider.
