Lenin's land (4)
I believe the answer is:
ussr
'lenin's land' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ussr that I've seen before include "Country established in1922 and dissolved in 1991, in short" , "Former association of communist republics" , "The Beatles? song 'Back in the . . . .'" , "Former union of socialist republics" , "Former Soviet Union" .)
