My Lords, I have Amendment 55CB in this group, which has the same effect as that of the noble Lord, Lord McKenzie, so I will not repeat what he said.
Viability is increasingly important, and not just in relation to Section 106 and the removal of obligations to make things viable. It is inherent in planning applications and local plans, in which pieces of land should be developed before others and in whether it is any longer possible, in old industrial towns such as in the area in which I live, to prioritise brownfield, formerly developed and regeneration sites over and above greenfield sites.
That is fundamental. The definitions which the Government, Planning Inspectorate and local authorities will use for viability on particular sites will also be fundamental. I look forward to future discussion on this.
