Players nearly dispossess left-winger (6)
I believe the answer is:
castro
'left-winger' is the definition.
(Fidel Castro, former Cuban leader)
'players nearly dispossess' is the wordplay.
I cannot really see how this works, but
'players' could be 'cast' (group of actors) and 'cast' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for castro that I've seen before include "Cuban president (past and present)" , "Old leader" , "Latin-American presidential co-star" , "Latin American dictator" , "Fidel . . . . . .,retired Cuban leader" .)
