Country's leading bottleshop employs nuns if needed (5)
I believe the answer is:
benin
'country's' is the definition.
(Benin is an example)
'leading bottleshop employs nuns if needed' is the wordplay.
'leading' says to take the initial letters (the leading letter of the word).
The initial letters of 'bottleshop employs nuns if needed' is 'BENIN'.
(Other definitions for benin that I've seen before include "West African state, formerly called Dahomey" , "City formerly known as Dahomey" , "Country W. of Nigeria" , "West Africa country, formerly a French colony" , "French-speaking West African country" .)
