The Prime Minister had a strong story to tell in his interview with this newspaper this week. Growth up, jobs up, real wages up. Radical and popular reform of welfare and schools now bedding in. And it looks as if he might be lucky as well. For Labour seems to be retreating to its comfort zone: it wants to fix energy markets, it wants to hit the rich, and some in the party even applaud the victory of the far, far Left in Greece.
