GLG to lose fund star to Soros

London-based hedge fund GLG Partners is on the brink of losing its star fund manager Robert Donald. Donald, who manages part of the £1.3bn European fund with Pierre Lagrange is mulling quitting GLG after six years, to team up with legendary financier George Soros. Soros, who famously made $1bn betting against sterling in 1992, is stepping up business in London after opening an affiliate office in Mayfair.  The departure of Donald will come as a further blow to GLG after losing top manager Greg Coffey last year.
