Classroom teaching unions are among 30 organisations which have complained to the Health Secretary Andrew Lansley about plans to get firms such as Mars, Cadbury and Coca-Cola to fund anti-obesity campaigns. In a letter to Mr Lansley, the groups condemned his aims, saying they are a threat to the health of British children. It added: “Voluntary approaches have repeatedly been shown to be ineffective and we would be deeply concerned if the Coalition government were to rely on industry self-regulation.”
