Rash logic confused Russian rulers (9)
I believe the answer is:
oligarchs
'russian rulers' is the definition.
'oligarchs' can be an answer for 'rulers'. I am not certain of the 'russian' bit.
'rash logic confused' is the wordplay.
'confused' indicates an anagram.
'rash'+'logic'='rashlogic'
'rashlogic' with letters rearranged gives 'OLIGARCHS'.
Can you help me to learn more?
(Other definitions for oligarchs that I've seen before include "governors" , "Influential businessmen" .)
