Diageo is facing a fight over its compensation plans for its leading executive, after a fifth of its shareholders voted against the group’s remuneration report. The shareholders, led by Co-operative Asset Management, are protesting against changes to the shares the drinks group awards to reward long-term performance. Issues raised by the shareholders included concerns about leaving provisions regarding share grants to chief executive Paul Walsh in the event he were to move on from Diageo. Co-operative Asset Management said at the group's annual general meeting it found the change and the lack of consultation “unacceptable”.
