Every local education authority shall furnish to the Minister of Health such particulars as he may from time to time require of the arrangements made by the authority in the exercise of their functions relating to medical inspection and medical treatment; and that Minister may give to any such authority such directions as to the discharge by the authority of those functions as appear to him to be expedient.

If arrangements are made for the exercise by the Minister of any functions conferred or imposed by this section on the Minister of Health, then, while such arrangements are in force, this section shall have effect in relation to such functions as if for the references therein to the Minister of Health there were substituted references to the Minister. Any directions given in the exercise of functions under this section may be varied or revoked by the Minister by whom those functions are for the time being exercisable.
