A Brie I distributed in part of Europe (6)
I believe the answer is:
iberia
'part of europe' is the definition.
('Iberia' is part of 'europe')
'a brie i distributed' is the wordplay.
'distributed' is an anagram indicator.
'a'+'brie'+'i'='abriei'
'abriei' anagrammed gives 'IBERIA'.
'in' acts as a link.
(Other definitions for iberia that I've seen before include "European region" , "Spanish/Portuguese peninsula" , "W. European peninsula" , "European peninsula comprising Spain and Portugal" , "Spain's national flag-carrying airline" .)
