Complaint as British price rises (4)
I believe the answer is:
beef
'complaint' is the definition.
(thesaurus)
'british price rises' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'price' becomes 'fee' (I've seen this in other clues).
'rises' shows that the letters should be reversed in order.
'fee' backwards is 'eef'.
'b'+'eef'='BEEF'
'as' acts as a link.
(Other definitions for beef that I've seen before include "nickname of US State" , "Complaint; muscle" , "Meat - complaint" , "Grumble - muscle" , "Complain; meat" .)
