I welcome what I think was a warm welcome to the idea of the English bus strategy. With all these things, I like to work in co-operation and make them work for the whole of the United Kingdom. That is why, for example, I put money into dustcarts in Glasgow that are hydrogen-run. I believe there are a dozen of them doing fantastic work and helping to develop the hydrogen economy. It is not quite as straightforward as the hon. Gentleman makes out; we all know that we can produce a hydrogen vehicle, but we also have to produce the hydrogen in a green enough way so that it is not in itself a polluting activity. A whole supply line is required for that, which is why in England I have assigned Teesside as the first hydrogen hub in the country, in order to help bring all those technologies together for all the different forms of transport.
I want to answer one question directly: the Barnett formula is attached to this, and the moneys will flow from that in the normal way.
