Er I'd just like to come back on three fairly brief points that er one of which was mentioned by Michael Courcier, two of which er relate to that, and were helpfully stimulated in discussion during the tea break, erm Michael Courcier, I think if I got him right, said, he did say we can't produce demographic forecasts for post two thousand and six but I think he was fairly guarded in saying it it wouldn't be wise or or whatever, erm I would suggest in this context, and in the context of, and I use the word emerging and I look for advice as to when emerging regional planning guidance, and when will be the end date of that regional planning guidance, I say we should be looking beyond two thousand and six, I say we can look beyond two thousand and six, and I would suggest we do it in the way of arrange, which would be highly appropriate way of doing it, not too dissimilar to road traffic forecasts, low medium and high growth, and if, to put the point simplistically, if we have arrived at a requirement figure of nine seven for Greater York for a specific period, if we were to either project that forward by five or ten years, obviously we couldn't just simply go rata, but if you took a low figure and you halved it on the basis of the make up, the demographic make up, of how the nine seven had been arrived at it would be possible to produce a range, that then relates to the question of a new settlement, and the alternatives during the period to two thousand and six, and beyond, of that new settlement, and I go back again to the greenbelt, it is vitally important to do that in the terms of a long term defined greenbelt, therefore again in that context, I would say it is highly desirable, if not necessary, to revisit the periphery of York, it has not been examined in a local plan, it has not been examined in terms of environmental impact, with all due respect to the Greater York working party their, the level of analysis of those peripheral blocks of land was fairly cursory, on a limited number of planning criteria, if a new settlement is to be assessed alongside expansion of Greater York we have to revisit it in much much greater detail.
