The firm, owned by Omnicom, had previously worked with clients including the Royal Highland and Agricultural Society of Scotland, Scottish Development International and mining giant Rio Tinto Alcan. John Saunders, regional president of the group, said: "Following a review of our operations in Edinburgh where we currently employ five staff, we have signalled our intention to close that office. "In future, all our business in Great Britain will be led from our office in London."
