King meets important Russian banker in country (5)
I believe the answer is:
rural
'country' is the definition.
(I know that country can be written as rural)
'king meets important russian banker' is the wordplay.
'king' becomes 'R' (abbreviation for rex, king in Latin).
'meets' is a charade indicator (letters next to each other).
'important russian banker' becomes 'ural' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'r'+'ural'='RURAL'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for rural that I've seen before include "Connected with farming" , "Characteristic of the countryside" , "Not urban" , "Characteristic of country life" , "Countrified" .)
