In January this year Simpson was responsible for carving up the £70 million global Adidas business between TBWA and the Amsterdam-based 180, in which TBWA has a stake. The appointments saw Leagas Delaney, Adidas' roster agency, removed from the business as the sportswear company attempted to take a more streamlined approach to give greater speed and coherence.
Simpson has worked for eight years outside the UK, first at Coca-Cola's head office in Atlanta for two years, where he oversaw the multimillion-pound budget for Coke, Fanta and Sprite in Europe, and latterly for Adidas, based in Amsterdam.
He started out as a graduate trainee at Ogilvy & Mather, soon moving to Bartle Bogle Hegarty. One of Simpson's clients as a BBH account director was Coke, which offered him the job of European advertising manager in 1995. While there he wrote the advertising brief for the "Eat football, sleep football, drink Coca-Cola campaign.
Simpson was unavailable for comment.
