Ideal to send back right person in authority (7)
I believe the answer is:
prefect
'person in authority' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
(Other definitions for prefect that I've seen before include "Schoolchild official" , "governor" , "Senior pupil with powers" , "Chief admin officer of a district in some countries" , "School senior" .)
