Fraudulent amusement centre ignoring first fine (6)
I believe the answer is:
unfair
'fraudulent' is the definition.
(fraudulent can mean unfair or wrong)
'amusement centre ignoring first fine' is the wordplay.
'amusement centre' becomes 'fun fair' (place for amusement or entertainment).
'ignoring' is a deletion indicator.
'first fine' becomes 'f' (1st letter of 'fine').
'funfair' with 'f' taken out is 'UNFAIR'.
(Other definitions for unfair that I've seen before include "not right" , "Not cricket?" , "Not just - lacking in beauty" , "Not equitable - or blonde?" , "out of order" .)
