Parts III and V shall be read as applying separately, and be administered separately, in England and Wales.
In particular, for England and Wales respectively—
Parts III and V shall be construed accordingly so that (for instance) references to authorities shall be read as references to those in England or Wales, as the case may be.
Any power conferred by this Act on the Secretary of State or the Treasury may be exercised differently for England and Wales, whether or not it is exercised separately; and this shall not prejudice the generality of sections 143(1) and 143A(2)(b).
