The petrol crisis is slowly abating, but some supermarket shelves are still empty. In the wake of Britain's three-day fuel crisis, retailers and producers fear the worst amid reports that it could be weeks before the petrol pumps are stocked and the delivery networks return to normal. The majority of protestors have now called off their blockades of the country's major oil refineries, saying that their aim was to put pressure on the government and they did not want to lose the sympathies of the public in their demands for a cut in fuel tax.
