From the lofty moral pinnacle reserved for those who have given up, quit, or otherwise eschewed smoking, I feel authorised to pronounce on the latest round of skirmishes in the world of tobacco. Tony Blair has announced that he is not averse to the idea of a ban on smoking in public, and might, should it prove to be true that there is no disadvantageous political smoke without a fire, insist that people who must do it, smoke in private.
