Their bank accounts are often misleading (7)
I believe the answer is:
anglers
'often misleading' is the definition.
I can't tell whether this definition defines the answer.
'their bank accounts' is the wordplay.
'their' becomes 'ang' (I can't justify this - if you can you should give a lot more credence to this answer).
'bank' says to hollow out the word (remove centre letters) (I've seen 'banks of' mean this (the banks are the sides of the word)).
'accounts' becomes 'letters' (letter is a kind of account).
'letters' with its middle removed is 'lers'.
'ang'+'lers'='ANGLERS'
'are' is the link.
Can you help me to learn more?
(Other definitions for anglers that I've seen before include "People fishing" , "Fishermen" .)
