New version of left-wing coup? (9)
I believe the answer is:
redaction
'new version' is the definition.
(a redacted version)
'left-wing coup?' is the wordplay.
'left wing' becomes 'red' (I've seen this in other clues).
'coup?' becomes 'action' (coup can mean a clever action or decision).
'red'+'action'='REDACTION'
'of' acts as a link.
(Other definitions for redaction that I've seen before include "process of censorship" , "text version" , "Amended written account" , "writing" , "that's needed if text is poor" .)
