Remove the following sentence "A marketing report as set out in Appendix C will be needed to show that the site is no longer needed for its current use." Alternative forms of evidence could be used to demonstrate value of current and proposed uses.

Not sound. With respect to the requirement for a marketing report, this may not be appropriate or required in all cases e.g. change of use for only a small part of a larger site, or change between different commercial use categories (again affecting small part of site). The point of this exceptional provision is to enable innovation from within an enterprise. What exactly would be marketed? Only the part of the site which is proposed for redevelopment/re-purposing or the whole site?
