Temporary employment group Randstad has extended its sponsorship contract with the AT&T Williams Formula 1 Team for a further three years. The new contract stipulates that the Dutch firm’s logo will appear on the front of the Williams car.

Chairman Ben Noteboom said worldwide branding was becoming increasingly important. Randstad is active in 12 of the 17 Grand Prix countries. Dutch bank ING sponsors the Renault team and car manufacturer Spyker bought the Midland team last year.
