Obviously Alastair Campbell is going to be all over the media in the next week with highly selective and self-serving extracts from his diaries. In the Observer, Ned Temko, who is never happier when being fed a story, tells us how the David Kelly affair was one of the low points of Campbell's life. The Sunday Times leads on a claim that Blair wanted to quit in 2002 but also lets us know how bad Campbell felt about Kelly.
Given that Campbell knew the government was in the wrong over the dossier all along, it isn't surprising that he felt a twinge of guilt. But what did he do? Went out and lied some more.
