A second influential advisory firm has come forward urging London Stock Exchange shareholders not to back an investor's bid to push the chairman out. Glass Lewis has told its clients that The Children's Investment Fund (TCI), run by hedge fund billionaire Sir Christopher Hohn, had "failed to present a sufficiently compelling case" to remove chairman Donald Brydon. The recommendation comes as a fresh blow to Sir Christopher, who is seeking shareholder support at a crunch investor meeting which will decide Mr Brydon's fate on December 19.
