Guillaume Rambourg, the star fund manager who left Gartmore more than six months ago to address an investigation by the Financial Services Authority, has been exonerated by the regulator and says he plans to return to a job in asset management.

A statement issued this morning by representatives of Rambourg said the former Gartmore manager had been notified that the FSA has concluded its investigation into his conduct as a fund manager at Gartmore, and will take no disciplinary action against him.
