Food summit heads for biofuels clash
Biofuel subsidies came under attack on Tuesday at the opening of the United Nations food summit in Rome as the head of the UN's Food and Agriculture Organisation claimed that "nobody" understood the diversion of food to fuel cars. The opening salvo is likely to set the tone for the next three days and put countries such as the US and Brazil, the world's largest biofuel producers, and also the European Union, on the defensive over their support of biofuel production.
