Fixed penalty discussed in connection with compromised ideals (9)
I believe the answer is:
finalised
'fixed penalty' is the definition.
The definition suggests a past participle verb which matches the answer.
'discussed in connection with compromised ideals' is the wordplay.
'discussed' becomes 'fin' (I can't justify this - if you can you should give a lot more credence to this answer).
'in connection with' is a charade indicator (letters next to each other).
'compromised' indicates anagramming the letters (I've seen 'compromising' mean this (compromise can mean change)).
'ideals' anagrammed gives 'alised'.
'fin'+'alised'='FINALISED'
(Other definitions for finalised that I've seen before include "settled" , "Completed" .)
