Scotland Bill

I respect the right hon. Gentleman's view that this is a process, and that he wants to reach what he calls home rule within the UK. I suspect that that probably means, in his mind and those of his honourable colleagues, effectively a federal position with full fiscal autonomy. I respect that position, but we do not have that before us, so why is he prepared to settle for a Bill that, while devolving speed limits for cars, will not allow the devolution of speed limits for cars drawing caravans? Why is he prepared to accept something so weak?
