Whether it's council houses or not, or whether it's social housing or not, you have got the dominance of this market of these large house builders who, as Mike Hedges has said, have no incentive to meet demand in full and who build in areas of very high demand and don't build houses that are affordable to those people who already live in those areas or live in areas just outside, to the north, which are lower income areas. So, as long as you've got this cartel dominating the market, then you're not going to be able to resolve the social housing problem either.

It was actually in 2013 that Persimmon said that they will no longer be building homes north of Pontypridd. They've said that publicly. Professor John Punter, professor of urban design at Cardiff University, said that there's no reason why we should be singling out particular areas of Wales not to build in. It comes down to the points that Mike Hedges has made: it's about the fact that once you start settling demand, then there's no reason to make a profit, there's less ability to make a profit, but also, need will never be met—need will never be met. So, I can see why it would be sensible to support Plaid Cymru's amendments, because the fact that we need to focus on social housing in areas that are not met by the demand curve, that are not meeting housing need, that is a must and therefore I can perfectly see that social housing needs to be a focus of the Welsh Government, and I urge the Welsh Government therefore to also support that.

It's not just an issue of housing, as has already been said, it's also an issue of the economy and growing the economy in those northern Valleys areas that I represent, but also in rural areas of Wales as well. The housing document that the Welsh Conservatives produced is interesting but the section on land supply doesn't talk about the cost of remediation. It isn't a costed document. The private sector cannot afford to meet the cost of remediation in many cases. The Economy, Infrastructure and Skills Committee are just about to start an inquiry into SMEs and house building, and I'm pretty sure that remediation of land will be a huge issue and it is a fact that local authorities have not got that funding either. I'm not a particularly partisan person, but austerity has certainly played a part in that lack of remediation of land, and the Conservatives must face up to that and take responsibility for it.

One of the other issues that I've raised has been the need for a strategic development plan. The First Minister mentioned—I think it was at his first First Minister's questions—the fact that the Cardiff capital region are now working on a strategic development plan and he's looking to see that operationalised. So, I say to the First Minister, 'Please, press that with the Cardiff capital region', and to the housing Minister, 'Press that with the capital region'; we need to see progress on that, and we need to see progress on that quickly. 

But the fact is, the debate we've had today is, in many ways, sensible, grown up, and slightly partisan too, as any debate that Leanne Wood is involved in will be, but it's not the kind of debate we would have out there in public. It isn't the kind of debate that we have during election times. Let's be sensible about this. If we're going to achieve a consensus, then we've got to stop using the kind of language that we use during the frenetic period of election campaigns.
