(Telecompaper) The leading shareholder of Telecom Italia (TIM), France's Vivendi, has announced that it will be calling for a meeting to change the board at the Italian operator. The move comes after TIM's board decided not to convene a shareholders meeting to confirm the appointment of Luigi Gubitosi as the company's new chief executive or choose new auditors, which Vivendi said went against "all rules proper corporate governance" and is "a source of disorganisation".
