Now we know why Jon Snow told us to watch. The Attorney General’s full advice on the legality of the war is out.

Tony Blair denied this document existed. Tony Blair said today “I have never told a lie. No. I don’t intend to go telling lies to people. I did not lie over Iraq.”

The paragraph above makes something plainly clear. Tony Blair lied to the public. Unquestionably. And, from comparing the full document to the summary, it looks like he may well have lied to Parliament as well – something much, much more serious. Surely even Bouncey Blair can’t ride this one out? If he is re-elected, he’s going to be facing an inquiry that, unlike the previous ones, he simply can’t fix. Unless, of course, he resigns.

The crisis at Labour HQ begins… If Alistair Campbell thought his job was almost done, he’s in for a nasty shock this evening.
