The move was a central plank of chief executive Stuart Rose's plans to revitalise the ailing High Street giant. By cancelling so many shares, it will enable M&S to improve, if not its profits, its earnings per share figures, a key ratio looked for by analysts in rating company's shares. It will also mean the group will be able to underpin future dividend payments as shareholders' payouts will not have to be distributed across so many shares to so many shareholders.
