A pack of newsmen (5)
I believe the answer is:
press
This clue is a double definition.
'a pack' is the first definition.
(thesaurus)
'newsmen' is the second definition.
(I've seen this in other clues)
'of' acts as a link.
(Other definitions for press that I've seen before include "rags together" , "Printing house" , "Weigh" , "Forcibly enlist" , "Crowd - papers" .)
