Bound to be in favour of 24 down having no money (8,3,4)
I believe the answer is:
strapped for cash
'no money' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'bound to be in favour of 24 down' is the wordplay.
'bound' becomes 'strapped' (strapping is a kind of binding).
'to be in favour of' becomes 'for' (I've seen this before).
'ah down' becomes 'cash' (I am not sure about this - if you are sure you should believe this answer much more).
'strapped'+'for'+'cash'='STRAPPED FOR CASH'
'having' is the link.
Can you help me to learn more?
(Other definitions for strapped for cash that I've seen before include "Bust" , "needing money" , "as an S & M prostitute?" , "very short of money?" , "not rolling in it" .)
