Any power to make regulations under this Act is exercisable by the Secretary of State by statutory instrument and may be exercised so as to make different provision for different purposes or for different cases (including different provision for different areas).

No regulations shall be made under section 4(5) unless a draft of the statutory instrument containing them has been laid before and approved by a resolution of each House of Parliament.

Subject to that, a statutory instrument containing regulations under this Act shall be subject to annulment in pursuance of a resolution of either House of Parliament.
