A crowd of journalists (5)
I believe the answer is:
press
I believe this clue is a double definition.
'a crowd' is the first definition.
(to press can mean to crowd around)
'journalists' is the second definition.
(the press can mean the newspaper industry)
'of' is the link.
(Other definitions for press that I've seen before include "Put creases in" , "part of the media" , "Crush - Fleet Street of old" , "Cupboard and printing machine" , "Produce record" .)
