Just two days ago, Gordon Brown was urging us all to stop wasting food and combat rising prices and a global shortage of provisions.

But yesterday the Prime Minister and other world leaders sat down to an 18-course gastronomic extravaganza at a G8 summit in Japan, which is focusing on the food crisis.

The dinner, and a six-course lunch, at the summit of leading industrialised nations on the island of Hokkaido, included delicacies such as caviar, milkfed lamb, sea urchin and tuna, with champagne and wines flown in from Europe and the U.S.

But the extravagance of the menus drew disapproval from critics who thought it hypocritical to produce such a lavish meal when world food supplies are under threat.

A Summit That's Hard to Swallow
