Mislead party on quota issue (13)
I believe the answer is:
consideration
'issue' is the definition.
(an issue that must be considered)
'mislead party on quota' is the wordplay.
'mislead' becomes 'con' (I've seen this in other clues).
'party on' becomes 'side' (eg a side or party in a contract. I am not sure about the 'on' bit.).
'quota' becomes 'ration' (I've seen this before).
'con'+'side'+'ration'='CONSIDERATION'
Can you help me to learn more?
(Other definitions for consideration that I've seen before include "examination" , "Kindness" , "Bearing in mind - payment" , "Study" , "A motive" .)
