Complaint from Belgium on raised charge (4)
I believe the answer is:
beef
'complaint' is the definition.
(thesaurus)
'belgium on raised charge' is the wordplay.
'belgium' becomes 'b' (international vehicle registration code).
'on' says to put letters next to each other.
'raised' says the letters should be written in reverse.
'charge' becomes 'fee' (fee is a kind of charge**).
'fee' reversed gives 'eef'.
'b'+'eef'='BEEF'
'from' acts as a link.
(Other definitions for beef that I've seen before include "Type of meat" , "Small errand" , "gripe" , "Argument" , "Muscle; meat; grievance" .)
