Levelling-up and Regeneration Bill

My Lords, I have a much less eloquent and much less exciting question to the proponents of Amendment 195, and certainly no fairy dust. If you are linking national targets to the local plan, what happens when national targets change during the five-year plan period? Does the plan have to be rewritten, do parts of it have to be rewritten, or do you have to wait until the end of the period and then apply the new target? It is a purely technical question and, as I say, much less exciting than some of the material we have just heard, but I would be grateful if the noble Lord, Lord Lansley, could help me with that.
