Mr. Jerry Grant:

In terms of Great Britain and Ireland and the kind of networks and old cities we have, the answer is "Yes". In terms of European cities that were rebuilt after the war and that mostly have plastic systems - polyethylene systems - the figure is much lower. Some of them are down to 10% while one or two are lower than that. There are huge variations across France. The figure in Paris is 10% while the figure nationally is 30%.
