PM almost nobody supports later (9)
I believe the answer is:
afternoon
'pm' is the definition.
(as in 4pm)
'almost nobody supports later' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'nobody' becomes 'no one' (not a single person).
'supports' is a charade indicator (letters next to each other) (bottom letters provide a support for the top ones).
'later' becomes 'after' (I've seen this before).
'noone' with its last letter taken away is 'noon'.
'noon' put after 'after' is 'AFTERNOON'.
(Other definitions for afternoon that I've seen before include "Midday to evening" , "Latter part of daylight hours" , "Period between morning and evening" , "Time of day" , "Post-midday" .)
