Entire, complete (7)
I believe the answer is:
plenary
This clue is a double definition.
'entire' is the first definition.
(thesaurus)
'complete' is the second definition.
(I've seen this before)
(Other definitions for plenary that I've seen before include "Attended by all members" , "Complete - with all present" , "Full meeting" , "unqualified" , "Meeting attended by whole conference" .)
