After copies of proposals have been sent to the Secretary of State and before they have been adopted by the local planning authority, the Secretary of State may direct that the proposals or any part of them shall be submitted to him for his approval.
If he gives such a direction—
the authority shall not take any further steps for the adoption of any of the proposals until the Secretary of State has given his decision on the proposals or the relevant part of the proposals; and
the proposals or the relevant part of the proposals shall not have effect unless approved by him and shall not require adoption by the authority under section 43.
