Old money calling attention to top Sterling with Euro concession (9)
I believe the answer is:
franchise
'concession' is the definition.
(I know that franchise is a type of concession)
'old money calling attention to top sterling with euro' is the wordplay.
I cannot quite understand how this works, but
'money' could be 'franc' (former currency of France) and 'franc' is present in the answer.
'euro' could be 'e' (E resembles the Euro symbol) and 'e' is found within the answer.
The remaining letters 'his' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for franchise that I've seen before include "Authorisation to sell a company's goods or services in a specified area" , "Commercial agreement giving marketing rights" , "The right to vote in elections" , "The right to vote in a parliamentary election." , "Rights assigned by authorisation" .)
