Communist leader is a flaming capitalist (7)
I believe the answer is:
redhead
'a flaming capitalist' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'communist leader' is the wordplay.
'communist' becomes 'red' (red can informally mean communist).
'leader' becomes 'head' (head is a kind of leader).
'red'+'head'='REDHEAD'
'is' is the link.
Can you help me to learn more?
(Other definitions for redhead that I've seen before include "Person with rufous hair" , "One with auburn hair" , "One with rufous hair" , "Auburn-haired person" , "diving duck?" .)
