The Minister may, after consultation with any local authority appearing to him to be concerned, by order made by statutory instrument repeal any provision of any local Act which appears to him to be unnecessary having regard to the provisions of this Act and may by that order make such amendments of that or any other local Act as appear to him to be necessary in consequence of the repeal and such transitional provision as appears to him to be necessary or expedient in connection with the matter:

Provided that, in the case of a provision of a local Act which appears to the Minister to be unnecessary having regard to the provisions of the last foregoing section, the power of repeal conferred by this subsection shall not be exercised without the consent of the local authorities for the area to which the proposed repeal extends.

For the purposes of this section the expression " Minister " means, as respect England and Wales, the Minister of Housing and Local Government and, as respects Scotland, the Secretary of State.
