(b)the reference in paragraph (a) of that subsection to an authorised person included a reference to a regulated person.
(2) The Authority may not exercise the power conferred on it by section 167 in relation to a former regulated person unless it considers that an investigation is reasonably required in connection with the exercise by the Authority of functions conferred on it by, or exercisable by the Authority by virtue of, this Order.
(3) The Secretary of State may not exercise the power conferred on him by section 167 in relation to a former regulated person.
