French refusal to welcome a European emperor (8)
I believe the answer is:
napoleon
'emperor' is the definition.
(Napoleon is an example)
'french refusal to welcome a european' is the wordplay.
'french refusal' becomes 'non' ('no' in French).
'to welcome' is an insertion indicator (inserted letters are welcomed in).
'european' becomes 'pole' (someone from Poland).
'a'+'pole'='apole'
'non' going around 'apole' is 'NAPOLEON'.
(Other definitions for napoleon that I've seen before include "French VIP" , "French emperor, d.1821" , "A pig farmer was chased by" , "The little French general" , "Cake" .)
