Llywydd, I'll do my best in the statement that I hope to publish shortly to restate some of the key components of the model, so that people can be clear about them. Let me just mention three in relation to the question that Nick Ramsay has asked: it's a key feature of the model that it allows the private sector to share in any profits of the private partner and to take up to 20 per cent equity in such schemes in order to do so. The model removes soft services from contracts—soft services such as cleaning and catering—and it removes equipment from the model as well, because of the experience that Nick Ramsay pointed to, and because equipment can be funded more efficiently from public capital. So, we have looked to learn the lessons of models elsewhere, particularly Scotland's not-for-profit distributing model, and to make sure that the model that we invent here in Wales learns those lessons and removes from it those components that have been particularly unsatisfactory in previous ways of working.
