Disgusted as Edward accepts gold throne (9)
I believe the answer is:
nauseated
'disgusted' is the definition.
('nauseate' can be a synonym of 'disgust')
'edward accepts gold throne' is the wordplay.
'edward' becomes 'Ned'.
'accepts' is an insertion indicator.
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'throne' becomes 'seat' (I've seen this in another clue).
'au'+'seat'='auseat'
'ned' placed around 'auseat' is 'NAUSEATED'.
'as' acts as a link.
(Other definitions for nauseated that I've seen before include "Disgusted" , "Sickened" , "Revolted" .)
