Ad Age: Grey London Management Team Quits in Surprise Exit

Nils Leonard, chairman and chief creative officer of WPP’s Grey London, has quit the agency alongside its CEO, Lucy Jameson, and managing director Natalie Graeme.

The trio are believed to be starting their own agency – a bold move at a time when the U.K. is facing long-term uncertainty triggered by last week’s Brexit vote.
