McLean, formerly chief client officer for the WPP firm's global solutions division, will lead global business development and the growth of global clients throughout the MEC network. There are no plans to fill his prior post.
"As an industry, we've gone through a period of consolidation. The next stage for both media and our clients is about supercharging or engendering organic growth," McLean says. "We need to unlock the value from all the things that have been consolidated."
McLean will report to Charles Courtier, CEO, Global, who said in a statement: "Delivering consistent growth is the biggest challenge for our clients and our business today. Andrew is the ideal person to lead this effort. His knowledge of our clients and his track record in building and growing business is outstanding."
