He will take responsibility for the agency's planning department, including staff from the agency's off-shoots such as Industry@Saatchi and Saatchi Interactive, which are being disbanded and embedded into the main agency. Team Saatchi will continue to operate independently.
Huntington will work alongside Kate Stanners and Paul Silburn, the creative partners, and the yet-to-be-appointed managing director. As a result, Chris Chalke, the chief strategy officer, will now become the director of strategy for EMEA and UK chairman.
Robert Senior, the UK chief executive of the SSF Group, said: "With Richard, we've just hired one of the best forward-thinking planners in the business."
Since United's closure earlier in the year, Huntington has been freelance. He was at the agency for ten years.
