Manages to keep India's spoils (5)
I believe the answer is:
ruins
'spoils' is the definition.
(ruining is a kind of spoiling)
'manages to keep india's' is the wordplay.
'manages' becomes 'runs' (I've seen this before).
'to keep' is an insertion indicator.
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'runs' going around 'i' is 'RUINS'.
(Other definitions for ruins that I've seen before include "Damaged remains (of building)" , "Mars" , "Damages beyond repair" , "Destroys" , "Derelict buildings" .)
