Dispute ends in aggro and indeed distress (4)
I believe the answer is:
odds
'dispute' is the definition.
(I've seen this before)
'ends in aggro and indeed distress' is the wordplay.
'ends in' suggests the final letters.
The last letters of 'aggro and indeed distress' are 'ODDS'.
(Other definitions for odds that I've seen before include "Betting likelihood" , "Betting figures" , "Starting price" , "Chances of occurrence" , "Chances, probability" .)
