A former Spanish prime minister and a former UK chancellor of the exchequer are among four heavyweight figures drafted in by UK hedge fund manager Centaurus Capital to its new advisory board.

José María Aznar, who oversaw Spain's adoption of the euro single currency during his two-term tenure as the country's prime minister between 1996 and 2004, and Ken Clarke, who was UK chancellor during the last Conservative government until 1997, have joined the advisory board at Centaurus, the hedge fund manager said in a statement today.
