A follower required here and there, perhaps (8)
I believe the answer is:
adherent
'a follower' is the definition.
(I know that adherent is a type of follower)
'and there perhaps' is the wordplay.
'perhaps' indicates an anagram.
'and'+'there'='andthere'
'andthere' is an anagram of 'ADHERENT'.
'required here' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for adherent that I've seen before include "Supporter, fan" , "lover" , "Weep" , "Devotee" , "advocate" .)
