Lads can broadcast malicious gossip (7)
I believe the answer is:
scandal
'malicious gossip' is the definition.
('scandal' can be a synonym of 'malicious gossip')
'lads can broadcast' is the wordplay.
'broadcast' indicates anagramming the letters.
'lads'+'can'='ladscan'
'ladscan' is an anagram of 'SCANDAL'.
(Other definitions for scandal that I've seen before include "It injures reputation" , "Disgraceful event" , "Something shameful or disgraceful, often public" , "Public outrage; gossip" , "subject for play school" .)
