Confectionery giant Cadbury is to be a sponsor of the 2012 London Olympic Games, the company announced today (20 October).

The Birmingham-based firm will supply all confectionery and packaged ice cream sold at venues and within the Olympic Park.

The deal gives Cadbury rights to use the London 2012 marks on product as well as marketing rights to Team GB and ParalympicsGB.

Todd Stitzer, CEO Cadbury plc, said: "We are extremely proud to be a supporter of the London 2012 Olympic Games and Paralympic Games. We have always strived to be a company that is both performance driven and values led - a philosophy that is at one with the long held ethos of the Games."

The sponsorship deal has prompted criticism from the National Obesity Forum, however, which said it is all part of the promotion of unhealthy food to children.

Currently there are seven tier one sponsors; Adidas, BP, British Airways, BT, EDF Energy, Lloyds TSB and Nortel, who donate around GBP40m (US$68.5m). Tier-two sponsors, of which Cadbury is one - donate around GBP20m.
