Levelling-up and Regeneration Bill

It was not a matter of the plans. The Minister has said that, as a matter of principle, the reason to reject the amendment was that flexibility is needed and that statutory provision for the automatic assumption to accept another plan should not be in the Bill. But Clause 86 says exactly that. I am trying to tease out why it is okay for one national plan but it is not okay for these local environment plans. What is the difference, as a matter of principle, if flexibility is required for local plans in every area, as the Minister said?
