Urged editor to support journalists (7)
I believe the answer is:
pressed
'urged' is the definition.
('press' can be a synonym of 'urge')
'editor to support journalists' is the wordplay.
'editor' becomes 'ed'.
'to support' means one lot of letters go next to another (in a down clue, some letters hold others up).
'journalists' becomes 'press' (I've seen this before).
'ed' after 'press' is 'PRESSED'.
(Other definitions for pressed that I've seen before include "Coerced" , "Ironed" , "Squeezed hard" , "crushed juice" , "Forced" .)
