Asset manager GLG Partners, who have registered excellent average returns of over 25% this year, has now appointed a former deputy governor of the Bank of England as an adviser, a further coup for the company.

GLG's top performing funds include the Alpha Select, that made 30% in the two years to June 30 - approximately spanning the credit crunch - and is up 19.5% this year, following 12% gains last year, investors said. This year, the company's select, income and growth funds made 41%, 28.4% and 22.3% respectively, although they lost between 30% and 41% last year, according to Bloomberg.
