You could say the Cuban leader's a ginger (7)
I believe the answer is:
redhead
'ginger' is the definition.
(both can mean someone with red hair)
'you could say the cuban leader's a' is the wordplay.
I cannot really understand how this works, but
'a' is within the answer.
'leader' could be 'red' (red is a kind of leader) and 'red' is present in the answer.
The remaining letters 'hed' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for redhead that I've seen before include "One with distinctive hair" , "Add here (anag)" , "Person with distinctive coloured hair" , "Bluey" , "'Carrot top'" .)
