Spies must keep wandering Bloom in country (8)
I believe the answer is:
colombia
'country' is the definition.
(Colombia is an example)
'spies must keep wandering bloom' is the wordplay.
'spies' becomes 'CIA' (Central Intelligence Agency).
'must keep' indicates putting letters inside.
'wandering' is an anagram indicator.
'bloom' anagrammed gives 'olomb'.
'cia' enclosing 'olomb' is 'COLOMBIA'.
'in' is the link.
(Other definitions for colombia that I've seen before include "South American Republic" , "S American state" , "Northwestern republic in South America" , "Coffee-exporting South American country" , "Bogot++ is its capital" .)
