It comes after the Ontario Teachers' Pension Plan called for a revamp of Vodafone's (VOD) board because of concerns about the group's strategy and track record on acquisitions. "My thoughts are that the only way the sum-of-parts discount would be narrowed would be through major changes of strategy and that would need new management including the CEO," the analyst adds.
