As has been suspected...

News (or something like it) from the Guardian:

Biofuels have forced global food prices up by 75% - far more than previously estimated - according to a confidential World Bank report obtained by the Guardian.

The damning unpublished assessment is based on the most detailed analysis of the crisis so far, carried out by an internationally-respected economist at global financial body.

The figure emphatically contradicts the US government's claims that plant-derived fuels contribute less than 3% to food-price rises. It will add to pressure on governments in Washington and across Europe, which have turned to plant-derived fuels to reduce emissions of greenhouse gases and reduce their dependence on imported oil.

More details at the Guardian - you can check there - but here's a particularly damning conclusion:

Senior development sources believe the report, completed in April, has not been published to avoid embarrassing President George Bush.

"It would put the World Bank in a political hot-spot with the White House," said one yesterday.

That's what happens when you put a Bush crony in at the World Bank... Heckuva job, Zoellie, eh?
