That's no longer a question. Today Tony Blair ploughed through his final Prime Minister's Questions, and in a few short moments he'll pop his feet up, settle back, relax, and look forward to a peaceful non-confrontational retirement... as a Mid-East envoy.

In the mean time he did still have that half-hour minefield to negotiate. We know the drill by now. First, the condolences to the members of the armed forces killed this week. Then the announcement of Prime Ministerial engagements. Except this week: "I will have no such further meetings later today, or any other day." Much laughter in the Commons.

Everyone seems to be wearing their front bench finery, particularly the likes of Ruth Kelly, who's dolled herself right up for this one. Gordon continues to look deeply bored by the whole process: he gives off an aura which suggests, in present mood, his answer to most PMQs would be, "Whatever".

And perhaps that attitude's rubbing off. To a Lib Dem question about the relationship between Church and State - "given his successor's reported views" - Blair's simple response: "I think I'm really not bothered about that one."

You know what, today does mark a paradigm shift on the front benches. For the first time in a long time, the Conservatives will have the better hair. Maggie's hair went a bit wild, John Major's retreated to a polar opposite, and several Tory leaders since have been entirely bereft - all the while, Tony's kept a refined mop, but one which suggests a hint of daring on occasion, even as it's greyed with age.

Gordon, by contrast, not only has boring hair, but hair that's already showing a considerable grey twinge. If he sticks around as long as Blair, it'll all be an arctic white by 2017.

And as we look across to the other side of the House, we find David Cameron's hair has miraculously Blairified itself! It seems to have perked up a bit from out of nowhere, as though it were arching a bushy eyebrow, and it's developed that upstanding greyish tweak without joining Brown in the box marked 'grey' entirely. Cameron is clearly the heir to Blair hair and this can only bode well for his election chances.

In the mean time PMQs continues, although it's like leaving a family gathering where you know the various strands of the family don't particularly like each other, but feel the need to be courteous. Messrs Cameron and Campbell pay their respects, Blair pays them back, and all the while everyone disassociates themselves from the other's politics.

There's that awkward tension in the air as these various family members share a cool, distant pat on the back resembling a hug. You stand by the door waiting to leap into the car and drive off, but someone else keeps insisting on paying a phenomenally insincere compliment.

Ian Paisley has the honour of the penultimate question. "I fully understand he was downcast, disappointed, angry and that perhaps he even lost his temper. But I want to say that he treated me with the greatest of courtesy. I disagreed with him on many things but we faced them, and I'm glad today that I can stand here and say to the Prime Minister: the people of Northern Ireland felt the same way as he felt, but we have made progress.

"Not as great a progress as I would like to see, but they are dedicated. The Unionist people I speak for are dedicated to see what has been started, concluded, so that every man and woman in Ulster will have the same rights, liberties and opportunities. I hope he'll look back and be able to say it was well worthwhile."

And if you're friends with Ian Paisley, you know it's time to leave.

Tony Blair's final words: "That is that. The end." Applause. Ovation from both sides. And with that the Prime Minister, doing well to hold back tears, shakes the hand of the Speaker of the House and departs.
