Communist leader in last revolution (6)
I believe the answer is:
stalin
'communist leader' is the definition.
'Stalin' can be an answer for 'leader' (Stalin is an example). I'm not sure about the 'communist' bit.
'in last revolution' is the wordplay.
'revolution' indicates anagramming the letters.
'in'+'last'='inlast'
'inlast' with letters rearranged gives 'STALIN'.
Can you help me to learn more?
(Other definitions for stalin that I've seen before include "Soviet dictator, d. 1953" , "Tyrannical dictator among Latins" , "Totalitarian Russian leader" , "Dread dictator among Latins" , "Lenin's successor" .)
