UPDATE 1-Ubisoft's staff share bonus scheme blocked by Vivendi

(Adds Vivendi statement)

PARIS, Sept 22 (Reuters) - Media conglomerate Vivendi has prevented a staff share awards scheme going ahead at Ubisoft, where it is the biggest shareholder, as it presses to get board representation at the French video games firm.

Vivendi, which has built up a 26.63 percent stake in Ubisoft since 2015, said that it had abstained from voting on a number of resolutions at the annual general meeting on Friday, including a motion to grant bonus shares to employees.

The resolution, which Ubisoft's top executives said was aimed at attracting and keeping talent, needed two thirds of the vote to pass.

But Vivendi, led by serial corporate raider Vincent Bollore, has long been at odds with Ubisoft's founding Guillemot family, which holds 15 percent of the shares and is opposed to Bollore increasing his influence at the firm.

But without board representation Vivendi said it was impossible to approve the resolutions submitted for voting.

"Vivendi regrets that, in defiance of all logical corporate governance, it has not yet been invited to be a member of the board of directors, even though it is the largest shareholder," the company said in a statement.

"It is clear that this complete lack of transparency from the family shareholders is depriving the company of significant support in its development and of proven expertise in the fields of media and entertainment," it added.
