The Secretary of State may by an agreement under this section delegate any relevant function which is not for the time being exercisable by the concessionaire to any person (other than a council to which it may be delegated under section 6(1) of the Highways Act 1980).

Functions delegated by an agreement under this section shall be exercised in accordance with such conditions as the Secretary of State may attach to the delegation; and the delegation shall end in accordance with the agreement.

In exercising a function delegated by an agreement under this section the person to whom it is delegated shall act as agent for the Secretary of State.

A person to whom a relevant function is delegated by an agreement under this section may enter into and carry into effect agreements with any person for any purpose connected with the exercise of the function.

Nothing in this section or in an agreement made under it shall prevent the Secretary of State from exercising a relevant function if he considers that it is in the public interest for him to do so.

Where a function may be delegated by an agreement under this section to a person other than a council to which subsection (1) of section 6 of the Highways Act 1980 applies, the function may also be delegated to such a council in accordance with that subsection (if it could not be apart from this subsection).
