Simon Mollan writes in Inner West: Another reason to vote for Ming – he is not a wonk that a "wonk" might not set the world alight, give us the profile we need. I disagree. There's been a lot of talk in both Labour and Tory parties in recent years of "blue sky thinking" yet it has all fallen flat because of the drudgery of parliament, government and opposition and the altar of focus group acceptance.

And the area most likely to give us that radical policy edge is the discovery, that Chris Huhne has already made for himself, that the economic orthodoxy we have been buried in since the seventies, the rise and apparent victory of monetarism, is not the fixed and rigid set of natural laws others would have us accept that it is. Some of us have spent most of our waking lives trying to persuade this party to listen to radical alternative viewpoints with few listeners, but Chris is one of those few.

I believe that smashing that consensus, particularly on the economic bases on which all British politics functions at present can give us the answer to so many pressing problems that we, with the others, are at present just tinkering - the pensions hole, world trade, the distribution of global wealth, offering what Bernard Lietaer calls "Sustainable Abundance". And smashing it will need someone who is economically literate enough to explain why it is not threatening, not frightening, and on the contrary liberating, ushering in a whole, at present practically unseen and certainly not understood, new economic order.

Now, I am not a hundred per cent certain that Chris has the balls for this task either. I know at least that he understands the arguments and is prepared to have them given an airing in the party. I'm clear it cannot be done from somewhere else on the front-bench, so important is it and potentially underpinning a huge amount of other policy. But he is the only one of the three that in my opinion could achieve that.

The current economic order in this country, and much of the western (at least) world, means that politicians are reduced to bidding for the PFI contract for deckchair management on the Titanic. We need someone who is literate enough to steer us away from the impending economic ice-bergs. And we have an opportunity to make the running on this. I'm only surprised that other economic radical, David Boyle, disagrees.
