Place in Spain has new agents after so long (8)
I believe the answer is:
valencia
'place in spain' is the definition.
'valencia' can be an answer for 'spain' (I've seen this before). I am not sure about the 'place in' bit.
'new agents after so long' is the wordplay.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'agents' becomes 'CIA' (Central Intelligence Agency).
'after' says to put letters next to each other.
'so long' becomes 'vale' (I've seen this in other clues).
'n'+'cia'='ncia'
'ncia' after 'vale' is 'VALENCIA'.
'has' acts as a link.
Can you help me to learn more?
(Other definitions for valencia that I've seen before include "port in the Med" , "Spanish city and region" , "European city" , "Spanish port" , "somewhere in Spain)" .)
