On this engrossing biography's original jacket in 2007, a perky, youthful Tory leader looked back at the reader, resembling a smoothy contestant in The Apprentice. The new edition's contrasting cover shows a sombre prime minister. The same well-researched early chapters (recalling A Dance to the Music of Time) on Cameron's untroubled journey via prep school, Eton and Oxford to Westminster appear in both versions, but in the updated edition suggest a different story. Before, he appeared poised to be embraced by the electorate, having escaped this gilded background; now he seems still detrimentally shaped by it, his failings as PM often attributable to an establishment mindset and image shared by his inner circle. As good as Andrew Rawnsley at getting insiders to talk candidly, the authors also emulate him in not softening criticism to soothe them, and are notably sharp on Cameron's botched election campaign, uncertain EU policy and disastrous wooing of Rupert Murdoch's executives.
