Maybe the most significant thing about Tony Blair's speech (watch it in full here) is not what was he said, but the tone with which he said it. The prime minister made it easy for his party to say goodbye to him - he made it easy for Labour to move on.
The speech could have been one of defiance aimed at those who've tried to bring him down, or one of anger towards Gordon Brown. It could have been a lecture to the next leader about what he should do. It was none of those things.
It is hard, against the backdrop of this speech - the nostalgic atmosphere, the crack in his voice, Blair's family gathered around him - to imagine the prime minister waiting more than half a year to hand in his resignation. And in theory, of course, he may not resign until next May, with a series of vital decisions to take, people to meet and things to achieve. It's quite surreal.
The unofficial agreement at this conference was supposed to be 'don't mention the war', don't mention the timetable. That only changed because Cherie, allegedly, slipped up yesterday. And wasn't it stylish how Blair dealt with that. Even I'm getting nostalgic.
