While thanking the hon. Gentleman for the letter, received today, in which he amplifies his extraordinary Written Answer of 12th February, may I ask him if he realises that this letter, although it amplifies, does not really clarify the matter very much, because he insists, as he has orally today, that "only Royal and postal anniversaries are marked by stamp issues" and that the Shakespeare anniversary is so marked because it is not an anniversary? When is an anniversary not an anniversary?
