WPP CMO Laurent Ezekiel Exits as Key Clients Move to Publicis

In a major shake-up in the advertising world, WPP’s Chief Marketing and Growth Officer Laurent Ezekiel has exited the company amid a wave of high-profile client departures. The sudden move comes as global giants Coca-Cola, Mars, and Paramount have shifted major parts of their business to rival agency Publicis Groupe.

Ezekiel, who joined WPP in 2019 from Publicis, played a key role in driving new business and managing global client relationships. His departure is seen as a blow to the company at a time when it faces mounting competitive pressure and questions over client retention.

The exits of Coca-Cola and Mars — long-standing accounts — signal deeper concerns about WPP’s ability to deliver integrated marketing services in an increasingly AI-driven and performance-focused industry. Industry insiders say the shift to Publicis reflects a preference for agility, innovation, and data-led strategies that clients are increasingly demanding.

WPP has yet to announce a replacement for Ezekiel or comment publicly on the recent account losses. Meanwhile, Publicis continues to strengthen its grip on the global advertising market, positioning itself as a go-to partner for major brands seeking transformation.
