The Fleet Street crowd? (5)
I believe the answer is:
press
I believe this clue is a double definition.
'the fleet street' is the first definition.
(I've seen this in other clues)
'crowd?' is the second definition.
(to press can mean to crowd around)
(Other definitions for press that I've seen before include "Urge strongly" , "Jam" , "(Of time) be short" , "part of the media" , "Enlist crew" .)
