Environment Bill

My Lords, I draw attention to my interest as a Church Commissioner, as set out in the register, and I wish to support what the noble Baroness just said: 30 years is rather a short period of time. I am grateful for the way the Minister, in proposing Amendments 86 and 88, is showing us the possibility of some flexibility in the future, but may I just tempt him a little further? What he is proposing would allow a future Government, by regulation, to change that period of 30 years—one would hope that it might go up to 50, 60 or perhaps even 125—but if they did, there would be nothing to prevent a subsequent Government reducing it back to 30 again. If we are to have a direction of travel in how long a site needs to be protected for, it should be one-way, without the possibility of going back down again. That could create a sort of planning blight, whereby somebody, particularly towards the end of a government cycle, might feel that, rather than making some land available for development, they can wait and hope that the period will be knocked back down to 30 years by the incoming Administration. Would the Minister be willing to think again so that, whatever period we set, any future changes would have to increase it rather than potentially allowing it to decrease?
