Ukrainian-born Marxist, expelled from the Soviet Union by Stalin in 1929 and later assassinated (7)

I believe the answer is:

trotsky

(Other definitions for trotsky that I've seen before include "Marxist leader" , "Bolshevik" , "Leon --, murdered Russian revolutionary" , "Leon --, early Marxist" , "Revolutionary ousted by Stalin" .)

I've seen this clue in The Guardian.
