Opinion: Perspective - Bollore's plan B installs a credible head at Euro.(Vincent Bollore)

Vincent Bollore, Havas' new chairman, has used the clarity often inherent in an external perspective to make change.

OK, his excellent plan A, the appointment of Jean-Marie Dru as the holding company's chief, didn't come to fruition, but his plan B is credible.

Attempting to secure the existent talent within Havas, he created a new executive committee four weeks ago. Notable for his absence on this management tier was Jim Heekin, the global head of Havas' principal property, Euro RSCG, which brings in more than 70 per cent of the holding company's revenue.

It was not surprising, therefore, when Havas confirmed this week that Heekin had resigned. Rumours of a move to Grey are rife, but there's still an ominous silence from WPP on the subject.

It appears Heekin was miscast at Euro, culturally speaking. He is a McCann Erickson veteran, with an American, pragmatic approach to advertising that can jar with the sometimes quirky nature of a French-owned network.

Euro staff are said to be chanting: 'The McCann era is dead.'

Ben Langdon, who runs Euro RSCG in London, and Marc Lepere, the network's global marketing director, both McCann recruits, should ally themselves quickly with Heekin's successor, David Jones. Aged 38, Jones must be the youngest network head ever, but those who know him are confident he will grow into the job.
