This is the big day for the chattering classes. Today at the Chilcot Inquiry the unreconciled anti-war left hopes Blair will trip up and effectively confess to war crimes, the commentariat are looking for closure – “the questions Blair must answer”, Hampstead and Islington intellectuals are looking for new material for after-dinner arguments. Cameroons will look on misty-eyed as the maestro shows how it is done. There will be something for everyone today. In the end, after six hours of testimony, Guido reckons Blair will walk away with his reputation unchanged. No one will change their mind as a result of Blair’s testimony today. Nevertheless for the political classes today is the super-bowl of political self-justification.
