Complaint of charge rejected by British (4)
I believe the answer is:
beef
'complaint' is the definition.
(thesaurus)
'charge rejected by british' is the wordplay.
'charge' becomes 'fee' (fee is a kind of charge**).
'rejected' says the letters should be written in reverse.
'by' says to put letters next to each other.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'fee' backwards is 'eef'.
'eef' put after 'b' is 'BEEF'.
'of' is the link.
(Other definitions for beef that I've seen before include "it's unacceptable for vegetarian" , "Muscle; meat; grievance" , "Complaint; muscle" , "Complain; meat" , "Complaint; strength" .)
