Firm with politician, legal or also acting immorally (9)
I believe the answer is:
complicit
'also acting immorally' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'firm with politician legal' is the wordplay.
'firm' becomes 'co' (abbreviation for company).
'with' means one lot of letters go next to another.
'politician' becomes 'MP' (Member of Parliament).
'legal' becomes 'licit' (similar in meaning).
'co'+'mp'+'licit'='COMPLICIT'
'or' acts as a link.
Can you help me to learn more?
(Other definitions for complicit that I've seen before include "Unlawfully involved" , "Involved with others in law-breaking" , "Being party to a crime" , "Sharing guilt" , "Involved with others in illegality" .)
