Greater London Authority Bill

My Lords, before my noble friend sits down, he has argued for economies of scale and prays in aid other cities in Europe and around the world. He does not seem to accept that the same could apply to London rather than breaking it up among 26 different boroughs. With all the new technologies, and if it is working so well elsewhere, why is it not happening here? He said that two-thirds of the boroughs are not meeting their targets. I do not see why a Greater London waste authority should not do the collecting as well. It may be subcontracted to the boroughs, but the authority would be responsible for it. Will my noble friend respond to that?
