Tim Lindsay, president of Interpublic Group network Lowe & Partners Worldwide, is stepping down.
London-based Lindsay, 47, will leave the agency in January to "evaluate new opportunities".
He will not be directly replaced. The regional executives who answered to Lindsay will now report to chief executive Jerry Judge.
In addition, Asia Pacific president Ian Creasey will become regional president for Europe, the Middle East and Africa.
