Hated vicar I escorted (7)
I believe the answer is:
reviled
'hated' is the definition.
'vicar i escorted' is the wordplay.
'vicar' becomes 'rev'.
'escorted' becomes 'led'.
'rev'+'i'+'led'='REVILED'
(Other definitions for reviled that I've seen before include "Maligned, vilified" , "Deliver (anag.)" , "Abusively criticised" , "Abused" .)
