To be candid, is unqualified (9)
I believe the answer is:
downright
I believe this clue is a double definition.
'to be candid' is the first definition.
(thesaurus)
'unqualified' is the second definition.
(thesaurus)
'is' is the link.
(Other definitions for downright that I've seen before include "Frank" , "rank" , "Absolutely!" , "Plain-spoken" , "Utter, arrant" .)
