Seen in Durham, bass adores diplomat (10)
I believe the answer is:
ambassador
'diplomat' is the definition.
(ambassador is a kind of diplomat)
'seen in durham bass adores' is the wordplay.
'seen in' indicates a hidden word.
'AMBASSADOR' can be found hidden inside 'durham bass adores'.
(Other definitions for ambassador that I've seen before include "foreign agent" , "voice?" , "Overseas diplomat" , "In a different case, he could be" , "Senior diplomat" .)
