The constitutional conversation is getting interesting.  Here The Guardian gets in its two cents (is that pence?):

Evolution not revolution is the way for constitutions to develop - except, perhaps, at times in history when a real revolution is under way. That was the message of justice secretary Jack Straw yesterday, as he spoke to a Washington audience. The tumultuous circumstances of American independence allowed the founding fathers to build up enduring rules from first principles; in more ordinary times a constitution written on a blank sheet will provide only a paper barrier against the abuse of power.
