Story about head of banks board (5)
I believe the answer is:
table
'board' is the definition.
('table' can be a synonym of 'board')
'story about head of banks' is the wordplay.
'story' becomes 'tale' ('tale' can be a synonym of 'story').
'about' is an insertion indicator.
'head of' indicates taking the first letters.
The initial letter of 'banks' is 'b'.
'tale' going around 'b' is 'TABLE'.
(Other definitions for table that I've seen before include "Flat surfaced piece of furniture" , "Food; flat gem surface" , "League --; multiplication --" , "Board; data list" , "Data arranged in rows and columns" .)
