Authorised airing, just what the doctor ordered? (14)
I believe the answer is:
constitutional
This clue is a double definition.
'authorised' is the first definition.
(thesaurus)
'airing just what the doctor ordered?' is the second definition.
(a walk or 'airing' which a doctor might recommend)
(Other definitions for constitutional that I've seen before include "authorised by the body politic" , "like our rulers" , "Healthy steps taken" , "Governmental" , "healthy exercise" .)
