Chennai leader remains with ready money (4)
I believe the answer is:
cash
'ready money' is the definition.
(I've seen this before)
'chennai leader remains' is the wordplay.
'leader' indicates taking the first letters.
'remains' becomes 'ash' (I've seen this before).
The first letter of 'chennai' is 'c'.
'c'+'ash'='CASH'
'with' is the link.
(Other definitions for cash that I've seen before include "notes, perhaps?" , "bread" , "Spondulicks" , "Hard currency" , "Funds" .)
