Disclaim any connection with the many possibly broadcast (6)
I believe the answer is:
disown
'disclaim any connection' is the definition.
'disown' can be an answer for 'disclaim' (I've seen this before). I am not sure about the 'any connection' bit.
'many possibly broadcast' is the wordplay.
'many' becomes 'd'.
'possibly' becomes 'i' (I can't explain this - if you can you should believe this answer much more).
'broadcast' becomes 'sown' (broadcast can mean to sow seeds).
'd'+'i'+'sown'='DISOWN'
'with the' is the link.
Can you help me to learn more?
(Other definitions for disown that I've seen before include "Repudiate, disclaim" , "Reject all connection or relationship with" , "Refuse to be associated with (a person)" , "Refuse responsibility for" , "Repudiate, cast off" .)
