European republic; capital Bucharest (7)
I believe the answer is:
romania
I believe this clue is a double definition.
'european republic' is the first definition.
(I've seen this before)
'capital bucharest' is the second definition.
(I know that Romania has the capital city Bucharest)
(Other definitions for romania that I've seen before include "European republic" , "Bucharest is its capital" , "Country of eastern Europe" , "Country in SE Europe" , "Oman air in the eastern European state" .)
