Revolutionary ways to collar boxer in upset (9)
I believe the answer is:
stalinist
'revolutionary ways' is the definition.
The definition suggests a singular noun which matches the answer.
'collar boxer in upset' is the wordplay.
I cannot really see how this works, but
'boxer' could be 'ali' (Muhammad Ali) and 'ali' is located in the answer.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Other definitions for stalinist that I've seen before include "Political hardliner" , "Communist" , "Soviet ideologue" .)
