Regret keeping vacant place for Indian bread (5)
I believe the answer is:
rupee
'indian bread' is the definition.
(I've seen this before)
'regret keeping vacant place' is the wordplay.
'regret' becomes 'rue' (to rue something is to regret it).
'keeping' indicates putting letters inside.
'vacant' says to hollow out the word (remove centre letters) (a vacant or emptied out form of the word).
'place' with its middle removed is 'pe'.
'rue' placed around 'pe' is 'RUPEE'.
'for' is the link.
(Other definitions for rupee that I've seen before include "Indian bread" , "cash" , "available without capital holds up" , "Indian money unit" , "foreign money" .)
