Subsection (2) applies if the Secretary of State is satisfied, after such inquiry as he considers appropriate, that—
as respects any part of England, the persons whose names are included in any pharmaceutical list are not such as to secure the adequate provision of pharmaceutical services in that ... part, or
for any other reason any considerable number of persons in any part of England are not receiving satisfactory services under the arrangements in force under this Chapter.
Where this subsection applies, the Secretary of State—
may authorise NHS England to make such other arrangements as he may approve, or may himself make such other arrangements, and
may dispense with any of the requirements of regulations made under this Part (other than Chapters 2 to 4) so far as appears to him necessary to meet exceptional circumstances and enable such arrangements to be made.
