King will have responsibility for all Ogilvy Group companies in the UK, including Ogilvy & Mather, Ogilvy Healthworld and Ogilvy Public Relations. Their chief executives will report to her.
Paul O’Donnell, who has been the UK chairman of Ogilvy Group since 2009, has taken the additional role of EAME chief executive of Ogilvy Group.
King has been the EAME chief executive of OgilvyOne since May 2012, when she was promoted from her position as the agency’s UK chief executive – a role she had held since 2008.
O’Donnell said: "It’s a fantastic time to be moving into this regional role. I have promoted Annette five times in her 14 years at the agency because it works. Her track record in all her previous roles speaks for itself."
