One charged following search and interrogation (8)
I believe the answer is:
question
'interrogation' is the definition.
(thesaurus)
'one charged following search' is the wordplay.
'one charged' becomes 'ion' (I've seen this in other clues).
'following' is a charade indicator (letters next to each other).
'search' becomes 'quest' (I've seen this before).
'ion' put after 'quest' is 'QUESTION'.
'and' acts as a link.
(Other definitions for question that I've seen before include "Interrogative sentence" , "dispute" , ""To be or not to be", for example" , "motion for debate" , "Grill" .)
