Emotional pang amongst right-wingers (6)
I believe the answer is:
twinge
'emotional pang' is the definition.
(I've seen this before)
'amongst right-wingers' is the wordplay.
'amongst' indicates a hidden word.
'TWINGE' is hidden in the letters of 'right wingers'.
(Other definitions for twinge that I've seen before include "A slight pain or pang" , "Sudden darting pain" , "Sudden stab of pain" , "Small pain eg from conscience" , "Sudden stinging pain" .)
