There was a moment - a minor incident - and I can't track it down. It was either Matthew Parris or Quentin Letts, watching Tony Blair perform in Parliament some years ago. The PM reacted scornfully to something he appeared to have heard from the Opposition benches, yet when the journalist asked his colleagues in the Press Gallery, nobody had heard that something. It seemed that Blair was simply indulging in brazen invention. A tiny incident, but revealing a character trait that has cost the country dearly.
In this week's Spectator, Charles Moore publishes an SMS text from a businesswoman friend, giving her immediate impressions of meeting David Cameron, and although she is clearly struck by the man's looks and personality, one little sentence jumped out at me: "Doesn't really listen." I think I know what she means, because it gels with how I read his body language every time I see him on the news: he is tightly focused on maintaining his grip on the Protean figure of Success, and will not be distracted. That has its dangers.
