MUMBAI: The Interpublic Group has elevated Harris Diamond from his position as chairman and CEO of IPG’s Constituency Management Group (CMG) to the same role at McCann Worldgroup, replacing Nick Brien.

Also, Luca Lindner and Gustavo Martinez have been given broader mandates within the company with significant geographic responsibilities and full oversight of McCann Erickson Advertising. The trio of Lindner, Martinez and Diamond will occupy a newly-created, three-person office of the Chairman for McCann Worldgroup.

In his new regional role, Lindner will also take charge of Middle East and Africa apart from the Americas while Martinez will add Asia Pacific responsibilities to his current title of president, Europe for McCann Worldgroup. As Diamond takes on his new position, the marketing services agencies that make up the Constituency Management Group will report directly into Interpublic management.

Interpublic chairman and CEO Michael I Roth said, “Harris understands the business needs of global CEOs, across a range of industries. He has a proven track record of effectively managing a portfolio of agencies and growing the top line. He has created a strong culture of collaboration, which is increasingly key in a marketing landscape that requires integration of services. And he brings a deep knowledge of McCann in light of the alignment between Worldgroup and a number of the agencies within CMG, such as Weber Shandwick and FutureBrand. In Luca and Gustavo, we are fortunate to have two outstanding, seasoned practitioners with a deep understanding of the advertising industry and McCann’s fundamental strengths. Over the past year, as co-Presidents of Global Clients for Worldgroup, they have played increasingly key roles in strengthening the agency’s relationships with major clients. Their continuing leadership and complementary skill set will be key to McCann’s future success. We thank Nick for his commitment and for driving change at McCann during his tenure.”
