Welcome to the rest of his politics question time with me, Rory Stewart, and me, Alistair Campbell.

Very good. Okay. Now, here we are, Joe Erwood to start us off, Alistair.

Joe Erwood asks, what decides an election? So he says, well, she, maybe, oppositions don't win elections, governments lose them.

Discuss, Alistair. I think you need both. I think you need both. I think that if you go back to 97, the country was fed up with the Tories. No doubt about that.

But to get the sort of big win that we got, there had to be the sense of the opposition also winning.

I think the reason why David Cameron, for example, didn't win in 2010, is that he was relying too much on the government losing and didn't actually do enough to get the opposition winning. So you definitely both.

So just to talk that through a little bit, and because this obviously relevant to how Keir Stammer, who's 20 points ahead on the opinion polls and looks like he can barely lose in the run against the Conservatives.

But I suppose what you'd say is the lesson is David Cameron was leading strongly in the opinion polls, not not by that amount, but leading strongly for two years and look like he was going to win a big majority.

And then when the event came, he didn't really break through against Gordon Brown in 2010.

What was your sense about the weakness of that campaign? What was David Cameron not brave enough, not clear enough? How was it he got that wrong?

I don't think that the public brought into the idea of there being an alternative government there. I think they're quite light camera, and I think they thought he was quite a credible figure.

But I just don't think there was a sense of him being... All the talks about him changing the Conservative Party rather than the country.

And I think there was a sense of them being against everybody, and that's sort of the country just decided, well let's just throw Nick Clegg into the mix and see if the coalition idea kind of works.

So I think it was that, whereas I think we did in 97 have a really strong positive agenda.

And the reason we talked last week about Keir Starmer's five missions, and actually he's written quite an interesting long piece in the new States from this week, where he's building on some of the things we talked about last week, where I think it really is about sort of...

You know, he's leading to getting to a place when the election comes, of those people who at the moment maybe aren't thinking too much about shifting vote, that actually when they get to the election, he wants there to be absolute clarity about what he wants those people to be thinking Labour stands for.

So I hope that's the plan, and I think at the moment Labour's lead is, I said this in this speech, I made the other day, I do think at the moment Labour's lead is largely driven or primarily driven by people being sick to death of the Tories, but they've got to keep going with the positive agenda, and they've got to develop it and pound it, because that ultimately is what will take them over the line.

Here's one for both of us, Stephen Clarke, what was the best speech you ever heard?

Well, I'm going to give a bit of a shout out, if I'm thinking about parliamentary speeches, to a very short speech, which Tom Tuggenhardt gave during the Afghan withdrawal.

And if you want to see it, it's easy, successful on YouTube. It was a really extraordinary example of a modern parliamentary speech, the time when I was beginning to lose faith in parliamentary rhetoric, because it was, it had a little bit of informality, it had raw emotion, it had a very serious argument, both a sort of argument about the character of Britain, and a policy argument about what we should have done, and it was delivered with real kind of sincerity and force.

How about you, what's your favourite speech?

I'm going to go for, if it's in Parliament, I'm going for John Smith against John Major. If people want to look it up, just look up the man with the non-Miders' touch.
