In terms of the land which is lost and will it be counted, er I would agree with David Allenby, in so in so far as where small sites are lost, they are in fact largely taken up in past land-take trends, but when a major site is lost, that at the moment forms part of the ninety one base of employment, and it it is something that we wouldn't have anticipated, therefore I think in terms of when we look at land availability figures and availability of supply erm we would have to look very carefully at land which is lost or significant land which is lost, or a significant number of jobs, it wouldn't necessary be added onto the structure plan requirement, but it could be deducted from the land availa land availability figures as land lost.
