Where there is a conflict between any of the provisions of a local plan in force for an area and the provisions of the relevant structure plan, the provisions of the local plan shall be taken to prevail for all purposes.
Where the structure plan is altered or replaced and the local plan is specified in a list under section 47(6) as a plan which does not conform to the structure plan as altered or replaced, subsection (1) does not apply until a proposal for the alteration of the local plan, or for its repeal and replacement, has been adopted or approved by the Secretary of State and the alteration, or replacement plan, has come into force.
