Llywydd, all of those are really important points that Peter Fox makes, and I know that he will speak from experience of having had to negotiate these agreements. He's right—there are many responsible building companies out there, with Tirion I referred to in the context of the Mill site in Cardiff being one of them. But there are too many examples, which he will know, and we could all of us quote from our own constituency responsibilities, where developers do not complete the deal that they themselves have entered into with local authorities. My colleague Julie James is very well aware of the need to make sure that agreements freely entered into, and planning permissions provided on the basis of those agreements, are honoured, in order to make sure that we achieve our ambitious targets for affordable and social housing here in Wales. And the Welsh Government continues to take a very direct and active part in shaping the policy platform for the future, to make sure that those responsibilities are properly discharged.
