I have to admit that the bicycle story put me off my stride. I was just settling down to pronounce on the tenth anniversary of Blair's premiership, and I was preparing for a dithyramb of destruction. I wasn't going to rain on Tony's parade; I was going to be a one-man hurricane of hatred, pouring squalls of cold water on anyone so foolish as to claim that Britain had got better on his watch.
Admit it. You'd not heard the word "dithyramb" before reading it there, had you?
