Wrigley believes Cadbury may have broken competition rules with the launch of a new line of gum. In two months, Cadbury has gained 12 percent of the UK gum market, and Wrigley may be upset about perceived positioning preference by retailers. While Wrigley dominated the chewing gum market, Cadbury is much more powerful in the confectionery market as a whole in the United Kingdom, and has greater influence with food retailers and newsagents.
