Former PM wrongly overlooked followers (6)
I believe the answer is:
church
'followers' is the definition.
(thesaurus)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for church that I've seen before include "fold" , "See 1" , "Place for public worship" , "A building for Christian worship" , "Ecclesiastical building" .)
