Broke relations in the street (5)
I believe the answer is:
skint
'broke' is the definition.
(both can mean struggling financially)
'relations in the street' is the wordplay.
'relations' becomes 'kin' (I've seen this before).
'in the' is an insertion indicator.
'street' becomes 'st' (abbreviation).
'kin' put inside 'st' is 'SKINT'.
(Other definitions for skint that I've seen before include "Hard-up" , "Strapped for cash" , "On one's uppers" , "Hard up (sl.)" , "Informally, having no money left" .)
