Where a designated vendor direction is given to a public communications provider, the Secretary of State must send a copy of the direction to the designated vendor or vendors specified in the direction, if or to the extent that it is reasonably practicable to do so.
The requirement in subsection (1) does not apply, in the case of a designated vendor, if the Secretary of State considers that sending a copy of the direction to that designated vendor would be contrary to the interests of national security.
The Secretary of State may exclude from the copy of the direction anything the disclosure of which the Secretary of State considers—
would, or would be likely to, prejudice to an unreasonable degree the commercial interests of any person; or
would be contrary to the interests of national security.
