In regard to enforcement, if publicans say they could not enforce a ban on smoking in their premises – such an obvious and visible thing – how in God's name can I believe that they can enforce rules about under age drinking, which are far more difficult to enforce given the difficulty establishing and proving people's age? If they do not have the will, the organisation or the ability to enforce a ban on smoking, then, manifestly, they will not have the will, the organisation or the ability to enforce a ban on under age drinking.
