Disputes with banks (4)
I believe the answer is:
rows
This clue is a double definition.
'disputes' is the first definition.
(row is a kind of dispute)
'banks' is the second definition.
(I've seen this before)
'with' acts as a link.
(Other definitions for rows that I've seen before include "Tiers" , "Disagreements" , "Quarrels; ranks" , "Propels into quarrels?" , "Arrangements side by side in lines" .)
