Lindsay Pattison has been named chief transformation officer of WPP with responsibility for getting its agencies to work more closely together for its top 50 clients.
Her appointment to the newly-created role comes at a pivotal time for WPP, which has reported two consecutive quarters of falling net sales and cut its forecasts three times this year.
Sir Martin Sorrell, the chief executive, has said he wants to simplify the group and get its agencies working more closely – a strategy he has dubbed "horizontality".
Pattison will keep her existing role as chief transformation officer of Group M, WPP's media-buying division, which she was given in May.
Her promotion makes her one of the most senior women within WPP, alongside the group chief counsel, Andrea Harris, and the global chief executive of J Walter Thompson, Tamara Ingram, and it signals the importance of Group M within the world’s biggest advertising group.
