Religious leader, a saint and a cult follower (5)
I believe the answer is:
rasta
'cult follower' is the definition.
(I've seen this before)
'religious leader a saint and a' is the wordplay.
'leader' suggests taking the first letters.
'saint' becomes 'st'.
'and' is a charade indicator (letters next to each other).
The initial letter of 'religious' is 'r'.
'r'+'a'+'st'+'a'='RASTA'
(Other definitions for rasta that I've seen before include "Religious adherent" , "Bob Marley, for one" , "Jamaican cult follower (informally)" , "Dreadlocked devotee" , "worshipper of Haile Selassie" .)
