Front man, mouthpiece (10)
I believe the answer is:
figurehead
I believe this clue is a double definition.
'front man' is the first definition.
(synonyms)
'mouthpiece' is the second definition.
(thesaurus)
(Other definitions for figurehead that I've seen before include "Nominal leader without much power" , "Nominal leader; carved bust at prow of ship" , "Front man" , "Person without real power" , "not as important as he looks?" .)
