Drink journalists keep down (8)
I believe the answer is:
suppress
'keep down' is the definition.
(thesaurus)
'drink journalists' is the wordplay.
'drink' becomes 'sup' (I've seen this before).
'journalists' becomes 'press' (I've seen this before).
'sup'+'press'='SUPPRESS'
(Other definitions for suppress that I've seen before include "Prevent from being publicised" , "squash" , "Restrain - crush" , "Stop publication of" , "Prevent from being circulated" .)
