JWT London has hired Tony Quinn, the head of planning and a managing partner at Leagas Delaney, as its head of planning.
Leagas has plugged the gap by appointing Matthew Palmer, the former WCRS planning director who has been freelancing at the agency since April, to the role of group planning director.
In his new position, Quinn will work with JWT's executive creative director, Russell Ramsey, on seven Nestle brands, including Kit Kat and Fruit Pastilles, while running a planning department of 23.
Palmer, meanwhile, will be responsible for developing Leagas' planning offering across all the group's international offices, including Hamburg, Rome, Milan and Prague.
Palmer will be based in London and will report to Margaret Johnson, Leagas' group chief executive. He joined WCRS in 2007 as the executive planning director from Saatchi & Saatchi, where he was the head of strategy.
Quinn replaces Hugh Duthie, who resigned from JWT in June 2007 to return to the US after joining the agency nine months earlier from TBWA\Chiat\Day New York.
Since Duthie's departure, Guy Murphy, JWT's global planning director, has assumed his responsibilities while the agency looked for a replacement.
Quinn joins JWT after ten years at Leagas, of which the past five were spent as the head of planning.
He said: "JWT has a big planning department with a bucketload of talent to lead. If you deconstruct it, it's all there: the people, the heritage and the clients."
Alison Burns, the JWT chief executive, added: "Tony is a fantastic planner who will make the department and agency stronger."
