IPG-owned agency network McCann Worldgroup has announced a restructuring of its leadership, with Daryl Lee set to become global chief executive officer as Chris Macdonald steps down.

Among other changes, Alex Lopez, global president and chief creative officer of McCann Worldgroup, is leaving the company. With his departure, McCann will create one global CCO position.

“As the CCO role shifts to one focused more on traditional advertising in their daily work, I am stepping aside to allow someone to take over who will bring the same passion to the job as I did,” Lopez said in a statement.
