Individuals in India abandoned by Indonesia (4)
I believe the answer is:
ones
'individuals' is the definition.
(I've seen this before)
'india abandoned by indonesia' is the wordplay.
'abandoned by' suggests deleting specific letters.
'indonesia' with 'india' removed is 'ONES'.
'in' acts as a link.
(Other definitions for ones that I've seen before include "(Of ship) returning to port of origin" , "Singletons" , "Units" , "1 & 1 & 1" , "Individuals" .)
