The Treasury may by order make provision as to the circumstances in which a person is, or is not, to be treated as carrying on—
a regulated claims management activity, or
an activity of a kind specified in an order under section 21(10B),
in Great Britain.
Subsections (2) to (5) of section 419 apply in relation to an order under subsection (1) as they apply in relation to an order under subsection (1) of that section, but as if the references to regulated activities in subsection (2) of that section were references to regulated claims management activities or, as the case may be, to activities of a kind specified in an order under section 21(10B).
