LONDON—Two-and-a-half years on from the merger of Omnicom-owned Gavin Anderson & Company and Swedish independent Kreab, the combined firm is restructuring its management team in what chief executive Richard Constant says is a response to client expectations for greater integration of financial communications and public affairs and more global services.

Constant will continue in his role as chief executive of Kreab Gavin Anderson, supported by two presidents: Sebastian Remoy, based in Brussels, who serves as head of the firm’s public affairs business; and Fergus Wylie, longtime head of the financial communications practice. The two will be responsible for developing new business and ensuring that existing business is served by the entire KGA network.

Charlotte Erkhammer, who was deputy chief executive, takes on a new role as executive vice chairman, and will be focused on client work, primarily in the Nordic markets.

In addition—in a move designed to provide stronger representation of the firm’s various geographic operations—the executive committee has been expanded to include Richard Barton (based in Hong Kong and also responsible for the firm’s China and Singapore offices); Ken Cronin (managing partner in London); Deborah Hayden (head of the Tokyo office); Karl Isaksson (managing partner, Brussels); Bengt Ludvigsson (managing partner, Sweden); Matti Saarinen (managing partner, Finland); Brian Tyson (responsible for the Australian operations); Morten Woldsdal (managing partner, Norway).
