Roos, formerly chief executive of L'Oréal Germany, was appointed as chief executive of Ipsos in July, and was set to take up the role from 28^th September, following a general shareholders’ meeting on 21^st September.

Ipsos and Roos have mutually agreed that she will not take up the position. 

Ipsos said in a statement that “in-depth discussions” have been taking place between current chief executive Didier Truchot and Roos since the appointment was announced.

The company added: “Last week, these discussions revealed deep discrepancies between the parties which led to this decision. Nonetheless, this disagreement does not bring into question Ipsos’ resolve to pursue the execution of its growth plan, embodied by the deployment, since July 2018, of its strategic initiative Total Understanding Project.”

The Ipsos board of directors has appointed Page, chief executive of Ipsos Mori, (pictured) as chief executive of the global business, replacing Truchot from 15^th November. Truchot will take up the role of chairman of the board of directors.

Page has led Ipsos Mori in the UK since 2009. Prior to that, he was a partner at Mori UK, leading the Social Research Institute, and was part of the team that led the management buyout and subsequent sale to Ipsos in 2005.

He is also a visiting professor at King’s College London and a council member at the Economic and Social Research Council.

Truchot said: “Ben is a great professional, capable of bringing together innovation and rigour, human capital and mastery of technology. Beyond the positive performance of the British business, Ben has played a central role in the creation and deployment of programmes that make Ipsos one of the most diversified and solid players in the research industry.

“I am convinced that Ben will accelerate Ipsos’ transformation and ensure the successful implementation of its projects to become a more effective partner for its clients, employees and shareholders”.
