Deposited pounds for charity! (4)
I believe the answer is:
laid
'deposited' is the definition.
(I've seen this before)
'pounds for charity' is the wordplay.
'pounds' becomes 'l' (L can represent the monetary pound**).
'for' says to put letters next to each other.
'charity' becomes 'aid' (I've seen this before).
'l'+'aid'='LAID'
(Other definitions for laid that I've seen before include "(Of dining table) set" , "tables may be?" , "The clutch must be" , "settled" , "Put down like dial" .)
