Perella Weinberg, the advisory firm set up by former Morgan Stanley rainmaker Joseph Perella, has landed its first hedge fund mandate after being hired by GLG Partners on a reverse acquisition to gain access to the public stock markets for the first time.

Perella Weinberg, which was set up in June last year, has the sole mandate to advise GLG on the reverse acquisition of Freedom Acquisition Holdings, a Delaware "blank check" holding company set up to buy other companies, according to a statement today from GLG.
