Chris got off to a poor start, telling us that we should vote for him because of his cv. Clegg told us what he wanted for the party. As a long time advocate of more hope and optimism in the Liberal Democrat message, I was impressed by this.

Chris then had to apologise for his dodgy dossier. He had clearly seen this one coming, and played a fairly effective routine (aided by Paxman) then using the old "break up the NHS" line to suggest that Clegg was causing confusion. However he had to concede that Clegg does not support a social insurance approach (at least I think he did).

But then - surprisingly - Huhne floundered on the economy and in responding to a question on Ming's (unfortunate) "soak the rich" remark. It was left to Clegg to produce the key point about cuts in income tax.

To the question "has there been too much immigration in the last five years" Clegg answered first: "no". Huhne then said "maybe" at some length. I thought he made some valid points, but it was hard to see what his overall point was.

Clegg then rejoined with the observation that "there are more Britons living abroad than foreigners living in Britain" and that there was no way the Liberal Democrats should be chasing the anti-immigrant vote.

This was the most interesting part of the discussion and I scored Clegg ahead on it - but I can well imagine that some will find Huhne's position more appealing.

On the inevitable coalition question undertandably neither wished to discuss terms. I thought Clegg did best in terms of listing issues and attitudes that he thought another party would have to take on board (and suggesting that no party willing to accept them existed). Personally I would deduct a mark for talking of a "a whole new style of politics" which doesn't seem to mean much to me. But Huhne failed to trouble the scorers on this one.

Do they like each other? Yes they do (or so they say).

What will stay in the casual voters mind? Well I doubt that many people have started looking for the Lib Dem website to sign up, but Clegg's message of optimism came over, reinforced by his emphasis on lower income tax for the lower paid, and his refusal to moan about immigration.

For Huhne I suspect the lasting impression will probably be his apologies for the dodgy dossier (he had to do this twice and literally put his hands up over it). He landed some sort of a blow on the NHS, but my impression was that he didn't leave voters with any clues as to why they ought to vote Liberal Democrat.

Overall I scored this a pretty clear win for Clegg - and possibly the best television exposure for the Liberal Democrats to come out of this campaign. But perhaps I am underestimating the force of negative messages.
