Roughly half of Italy's Mediaset investors set to vote on governance changes

MILAN (Reuters) - Shareholders representing just under half of Mediaset's capital were present on Thursday at an extraordinary meeting the called to approve governance changes at Italy's biggest private broadcaster, one shareholder said.

Shareholders of the Milan-based TV group, which is 39.5 percent owned by former Italian Prime Minister Silvio Berlusconi, are asked to vote on a proposal to cut the maximum number of board seats to 15 from 21 and to change the way directors are appointed.

If approved by two thirds of shareholders present, the changes are expected to strengthen the Berlusconi family's grip on the group.
