Politics - I keep telling my students - is a nasty business, in which principle counts for little and pragmatism - cynical and often heartless - counts for a great deal.
The late Michael Foot, for instance, was a man of principle, and therefore a very unsuccessful politician. Tony Blair, by contrast, was a survivor, a Thatcherite leader of an ostensibly socialist party. Behind him, waiting in the wings, was of course Gordon Brown, a professional student of politics as well as a consummate practitioner.
