Nothing in bid at a passport page content (7)
I believe the answer is:
biodata
'passport page content' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'nothing in bid at a' is the wordplay.
'nothing' becomes 'O' (looks like zero - 0).
'in' indicates putting letters inside.
'o' put within 'bid' is 'biod'.
'biod'+'at'+'a'='BIODATA'
Can you help me to learn more?
(Other definitions for biodata that I've seen before include "Facts of life" , "Biographical details" .)
