French corporate raider Vincent Bolloré, having ingested Havas, continues to build his stake in Aegis Group.

Last month Bolloré revealed he held a 6% stake in the London-headquartered media and research agency operation [WAMN: 05-Aug-05]. Yesterday, Tuesday, he announced it had been increased by a further 2.04%.

Analysts and media observers interpret the move as signalling a battle with Publicis Groupe for control of Aegis.

But other onlookers wonder if the canny Bolloré isn't simply attempting to maximise the value of his holding by nudging up the share price - which yesterday closed at £1.385, below the £1.40 indicative price proposed by Publicis.
