65.Section 18 makes provision for the application of section 17 with modifications in relation to persons who are listed authorities by virtue of being family health service providers in Wales or independent providers in Wales. The effect of the modifications is that it is the person with whom the provider contracted or made arrangements (or to whom he/she undertook) to provide the relevant services on whom the publicity requirements fall, rather than on the listed authority (i.e. the family health service provider or independent provider).
