Roy Ben, It sound as if The Birmingham council, have shot themselves in the foot, Maybe they forget that it's not just Cadbury any more, but most of the sweets and biscuits industry, and if you mess with one you mess with them all.
Like most little people who work in local government, they are full of themselves, and they have the power, but not the responsibility, which makes them dangerous.
They can say and do what they like and theres no come back on them if it goes wrong, it comes back onto you... the tax payer, ( and its a case of the few that carry the many in local government )
If the local council interfear to much, then I'm sure Cadbury will pick up their roots and move on,.........John 2000
