As the hon. Gentleman will know, we are working on a food strategy that will address all these issues across the food supply chain and some of the other challenges around the food industry, too. On his specific question, as I have said, we are largely self-sufficient in wheat production. We import some wheat from Canada. Most of our bread manufacturers therefore have British or Canadian wheat in their bread. We have modelled the impact of the increase in commodity prices on the price of a loaf of bread, and because wheat only represents about 10% of the cost of a loaf of bread, the impact is actually quite modest. A much bigger impact is likely to be the increase in fuel costs, since the cost of delivering bread is the biggest cost they face.
