Enough with the posturing: show us the money. That is the spirit supposed to inspire the ministers meeting in London today in the latest instalment of the "Doha round" of World Trade Organisation talks.

Over the next two days, ministers from the "group of six" WTO members - the European Union, US, India, Brazil, Japan and Australia - will try to begin narrowing down the vast range of potential deals. Seeking to avoid a replay of December's ministerial meeting in Hong Kong, which comprised mainly a fruitless exchange from entrenched positions, ministers are supposed to get down to specifics.
