Point in Moscow established (4)
I believe the answer is:
west
'point' is the definition.
(west is a kind of point)
'in moscow established' is the wordplay.
'in' indicates the answer is hidden within the clue.
'WEST' is hidden within 'moscow established'.
(Other definitions for west that I've seen before include "One Direction" , "Dog (from Argyll?)" , "'Go ___ , young man'" , "Colombian with brews (anag)" , "Occident" .)
