Right to vote of a man in European country (9)
I believe the answer is:
franchise
'right to vote' is the definition.
('franchise' can be a synonym of 'right to vote')
'a man in european country' is the wordplay.
'a man' becomes 'his' (I can't justify this - if you can you should give a lot more credence to this answer).
'in' is an insertion indicator.
'european country' becomes 'france' (France is an example).
'his' going inside 'france' is 'FRANCHISE'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for franchise that I've seen before include "Rights assigned by authorisation" , "For citizen, right" , "Authorisation to sell a company's goods or services in a specified area" , "suffrage" , "permit being provided" .)
