Leader in Caribbean, a revolutionary sort (6)
I believe the answer is:
castro
'leader' is the definition.
(I know that Castro is a socialist)
'caribbean a revolutionary sort' is the wordplay.
'caribbean' becomes 'c' (this might be a standard abbreviation which I don't know about).
'revolutionary' is an anagram indicator.
'sort' with letters rearranged gives 'stro'.
'c'+'a'+'stro'='CASTRO'
'in' is the link.
Can you help me to learn more?
(Other definitions for castro that I've seen before include "Fidel -, former Cuban leader" , "He's late" , "Cuban dictator" , "Fidel ......, Cuban chief" , "revolutionary leader" .)
