Dewhurst (pictured) has been managing partner at Hall & Partners since 2016, leading the company’s consumer division in Europe. Prior to joining the agency as senior research director in 2012, he worked at the Central Office of Information and Ipsos MORI.

In his new role, Dewhurst will lead the financial services and technology division for Kantar TNS UK and sit on the board. He will be responsible for thought leadership, client relationships, talent management and financial performance.

Amy Cashman, who previously led the financial services and technology team, was promoted to UK managing director of Kantar TNS in January.

Cashman said: “Martin has an outstanding background in insights and research developed over 18 years, with both extensive client and agency-side experience across a wide range of clients, and a successful track record in leading and motivating teams.”
