Sadiq Khan is committed to protecting both industrial workspace and the Greenbelt. 

In his talk Colin Wilson suggests there is potential for using areas of poor quality Greenbelt, particularly that adjacent to existing industrial clusters and motorway infrastructure for industrial land, while at the same time  freeing up industrial sites near railway stations to deliver much needed housing. The gains in land value could be invested in improving the Greenbelt, providing more affordable housing and making a compelling business case to The Treasury to fund schemes like Crossrail 2. Is there a more rational approach to land use allocation and transport investment? And even if there is will politicians ever back it?
