Slumdog Millionaire city (4)
I believe the answer is:
agra
'slumdog millionaire city' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for agra that I've seen before include "tourist centre" , "Site of the Taj Mahal" , "Indian city, capital of the Mogul empire until 1658" , "Indian masterpiece" , "Taj Mahal city" .)
