Stirrer primarily targeting earner in Vladivostok, say? (12)
I believe the answer is:
troublemaker
'stirrer' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for troublemaker that I've seen before include "Inciter of unrest" , "Incendiary" , "One inciting unrest" , "Cause of conflict" , "Person stirring up problems" .)
