Hush up drink with journalists (8)
I believe the answer is:
suppress
'hush up' is the definition.
(thesaurus)
'drink with journalists' is the wordplay.
'drink' becomes 'sup' (I've seen this before).
'with' means one lot of letters go next to another.
'journalists' becomes 'press' (I've seen this before).
'sup'+'press'='SUPPRESS'
(Other definitions for suppress that I've seen before include "Prevent (from being published)" , "Prevent from being circulated" , "Crush, put down" , "Stifle, feelings or rebellion" , "Put down by force or authority" .)
