Newsmen in force (5)
I believe the answer is:
press
This clue is a double definition.
'newsmen' is the first definition.
(I've seen this in other clues)
'force' is the second definition.
(I know this)
'in' acts as a link.
(Other definitions for press that I've seen before include "Squeeze together" , "needed to avoid crooked racket" , "Printing house" , "newspapermen?" , "Cupboard for storing clothes" .)
