A long tale I edited (for a charge) (10)
I believe the answer is:
allegation
'a charge' is the definition.
(allegation is a kind of charge)
'a long tale i edited' is the wordplay.
'edited' is an anagram indicator.
'long'+'tale'+'i'='longtalei'
'longtalei' is an anagram of 'llegation'.
'a'+'llegation'='ALLEGATION'
'for' acts as a link.
(Other definitions for allegation that I've seen before include "Accusal" , "Unfounded claim" .)
