BBH London has elevated Ian Heartfield to the role of chief creative officer as his former joint executive creative director, Anthony Austin, departs the business.
In a statement, the London shop said Austin has left to ‘pursue opportunities outside of BBH’.
The duo originally replaced Nick Gill as ECDs in July 2017.
The reshuffle will see Heartfield act as the single point of creative leadership at the agency. A veteran of Ogilvy, AMV BBDO and Fallon, the creative has overseen work such as Absolut’s ‘One Night’ and Audi’s ‘Clowns’.
"There is real creative momentum at BBH right now and we are making and winning projects of a much more diverse nature than ever before,” said Heartfield. “But this is just the beginning. We have some important decisions to make as we look to the future and shape the department and agency accordingly.
"To be the creative lead at a time of change like this is incredibly exciting and a big responsibility, one I don't intend to take lightly."
Pelle Sjoenell, BBH's worldwide chief creative officer, added: "I'm very excited for the future of creativity in London under Ian's brilliant leadership. I would also like to thank Anthony for his contribution to BBH in both his launch of our very successful in house production company Black Sheep Studios, and our recent creative highlights.
"I wish him all the best in his next role."
