JWT has appointed Toby Hoare to the position of executive chairman, following last week's news that Simon Bolton is stepping down as its chief executive.
Hoare will now oversee any resulting changes to the embattled agency's senior management team. However, he said he will not hurry to make any fresh appointments.
Bolton, who ran JWT for five years, is still discussing his role within the network.
In addition to taking on responsibility for the whole JWT group in the UK, Hoare will continue to run the global HSBC business, an account he was instrumental in winning and has led for the past two years as the chief executive of WPP's Team HSBC.
He will work closely with Craig Davis, JWT's worldwide chief creative officer, and Guy Chauvel, the newly appointed executive vice-president and chief client officer for multinational accounts. Chauvel has taken over from David Lamb, who has left the agency to become the head of marketing for JWT's Diamond Trading Company client.
Bob Jeffrey, the worldwide chairman and chief executive of JWT, said: "Toby's leadership role on HSBC demon- strates that he is a champion of ambitious thinking on a grand scale. With Toby and a solid leadership team in place, the agency will become a formidable force."
Hoare joined WPP in 2003 when the holding company acquired Bates, where he was the chairman for Europe, the Middle East and Africa.
He became Bates' UK chairman in 2001 when he joined from Young & Rubicam.
He left Y&R when it was merged with Rainey Kelly Campbell Roalfe.
