But, Llywydd, let me make this final point: the format of this document is important. We want to stimulate an urgent debate, but we do not claim to have all the answers. So what we have put forward is a set of propositions, and we want the UK Government, and of course others, to engage with them. It is the proper purpose of politics to argue out competing propositions and different views of our futures. In this document, we say, 'Here is our version of how that future should be saved.' To others here in Wales and in other parts of the United Kingdom, we say, 'Please let that debate begin.' Diolch yn fawr.
