The Secretary of State must review a designated vendor direction from time to time.
The Secretary of State may—
vary a designated vendor direction;
revoke a designated vendor direction (whether wholly or in part).
The Secretary of State may vary a designated vendor direction only if—
the Secretary of State considers that the direction as varied is necessary in the interests of national security; and
the Secretary of State considers that the requirements imposed by the direction as varied are proportionate to what is sought to be achieved by the direction.
Before varying a designated vendor direction, the Secretary of State must consult—
the public communications provider or providers which would be subject to the direction as proposed to be varied, and
the person or persons who would be affected as a designated vendor or vendors by the direction as proposed to be varied,
so far as it is reasonably practicable to do so.
The requirement in subsection (4) does not apply if or to extent that the Secretary of State considers that consultation would be contrary to the interests of national security.
