Part 3: Regulatory Enforcement and Sanctions Act Section 28B: Other regulators required to act consistently with primary authority advice  etc
This section provides that "complementary regulators" must act consistently with primary authority advice and guidance in the exercise of their "designated functions" in relation to a regulated person of a member of a regulated group, in so far as it was aware that the person is a member of a regulated group and as far as is possible to do so in accordance with its other functions (subsections (2) to (4)). Subsection (5) defines primary authority advice and guidance as advice and guidance issued by a primary authority under section 24A and inspection plans made by the primary authority under section 26A.
	Under subsection (1), a "complementary regulator" is defined as a person who has regulatory functions and who is specified in regulations made by the Secretary of State. The consent of the Welsh Ministers is required where the "complementary regulator" exercises functions that relate only to devolved Welsh matters (subsection (8)).
	Under subsections (1)(b) and (9), the Secretary of State must specify in regulations the "designated functions" exercised by the complementary regulator. A designated function must be a "partnership function" (as defined in section 23A(2)) or equivalent to such a function but must not be a "relevant function" (defined in section 22C) of the complementary regulator. This means that, in relation to the designated function, the complementary regulator could not be a "qualifying regulator" eligible for nomination as a primary authority under section 23A. The designated function must be exercisable by the complementary regulator in relation to the regulated person or member of the regulated group.
	Under subsection (11) the regulations may not include regulatory functions exercisable in Scotland, unless those functions are reserved matters and may not include regulatory functions in Northern Ireland that are transferred matters. The consent of the Welsh Ministers is required to include a regulatory function, so far as is exercisable in Wales, which relates to a devolved Welsh matter.
