(2) The way in which the power to vary is exercised must be such that the resulting—
(a)varied direction, or
(b)where the earlier direction was part of a set of transitional directions, set of directions as varied,
could be given by revoking existing, and giving new, transitional directions.
(3) Where a transitional direction has been given to two or more particular persons, or to persons of a description specified in the direction, the power to vary it may be exercised in relation to all, some or any one of those persons.
(4) Regulation 200(7) (meaning of “set”) applies also for the purposes of paragraph (2).
