Mogul capital of India (4)
I believe the answer is:
agra
'mogul capital of india' 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 "vicinity of mausoleum" , "mausoleum site" , "Foreign city" , "Site of the TajMahal" , "City in India" .)
