Before taking the newly created role, Ros was chairman at TNS, but ran the business as CEO following its acquisition by WPP and its subsequent merger with WPP-owned Research International.

News of Ros’s appointment at Creston follows the announcement last week that group CEO Don Elgie was retiring, to be replaced by CFO Barrie Brien. Several weeks before, head of Creston Insight, Keith Bates, had also announced his departure.

Ros said: “I am excited to be joining Creston at a time of unprecedented change within the insights industry. I am looking forward to helping the group’s insight companies further exploit their exceptional client focus, and to build on the division’s growth in this dynamic and creative industry.”
