Levelling-up and Regeneration Bill

I want to raise with my hon. Friend an issue about local democracy and local plans, which the hon. Member for The Cotswolds (Sir Geoffrey Clifton-Brown) mentioned. A local plan must be consistent with national planning policies, and correctly so. However, if there is a conflict between a local plan and national development management policy, national policy holds sway and is given priority in any determination. How can it be that a local plan can be drawn up in full consultation with the local community, but if the Secretary of State later decides to change the national policy, it will override the consulted-upon local plan?
