While we associate the working class with virtues like honesty, hard work and community spirit, the middle class divides into two tribes who dislike and distrust each other. The Islington Tendency are the infamous chattering classes, self-obsessed and silly, parading their Leftish values while living in luxury and sending their children to private schools. The Blairs - as former residents of N1 - are still parodied as belonging to this group. What we might call the Surbiton Tendency as personified by Hyacinth Bucket or Jerry and Margot from The Good Life, leaning over the drinks cabinet to peep suspiciously through the lace curtains at their neighbours' new lawn mower. They are old fashioned, uptight, narrowminded, and - let's face it - deadly dull. Tony Blair's mistake was to tell the rest of us we were joining a class we don't really like very much.
