My Lords, Amendment 97A, tabled by the noble Lord, Lord Lansley, seeks to ensure that any spatial development strategy that had been prepared by an authority remains in place for the strategy area following the restructure of the strategic planning authority; the strategy could not be replaced or substantially altered within five years of its adoption unless the Secretary of State authorised a strategic planning authority to do so. Given that the Government are currently undertaking an ambitious programme of local government reorganisation in England, I understand why the noble Lord seeks to make provision to account for this and ensure a degree of continuity for an operative spatial development strategy.

However, new Section 12T empowers the Secretary of State to include transitional provisions in strategic planning board regulations. This power complements existing powers to make transitional provision in regulations to reflect changes to local government organisation. If a local government reorganisation leads to uncertainty over the boundaries of a spatial development strategy or its applicability to an area, it is more suitable to address this through tailored transitional provision in regulations rather than through primary legislation. This means that the effects of local government reorganisation can be considered on a case-by-case basis.

Preventing a strategic planning authority from replacing or significantly revising its spatial development strategy until five years after its adoption following local government reorganisation would restrict its ability to respond to major national policy changes or new major investment in its area. Strategic planning authorities are well placed to determine when updates to their strategies are necessary and should retain the discretion to do so. Given this, I would respectfully ask the noble Lord to withdraw his amendment.
