Suspended journalist on board (6)
I believe the answer is:
stayed
'suspended' is the definition.
(stay can mean to postpone or suspend)
'journalist on board' is the wordplay.
'journalist' becomes 'ed' (short for editor).
'on' is a charade indicator (letters next to each other).
'board' becomes 'stay' (board can mean to stay in a place).
'ed' put after 'stay' is 'STAYED'.
(Other definitions for stayed that I've seen before include "Remained; guyed" , "Remained or posponed" , "Didn't go" , "Kept going - or didn't" , "Remained; steadied" .)
