Cameron’s tragic flaw

Premierships do not end in failure, as Enoch Powell once asserted, but in tragedy. They start with a beaming figure disappearing behind the door of No. 10 — even Edward Heath, immortalised now as the Incredible Sulk, entered with a radiant grin. And they end with a haunted shadow of a politician creeping out to a waiting car, his every character flaw having been chiselled to destruction.
