One piece of news – or a couple (4)
I believe the answer is:
item
This clue is a double definition.
'one piece of news' is the first definition.
(I've seen this in another clue)
'a couple' is the second definition.
(a romantic couple are 'an item')
(Other definitions for item that I've seen before include "Time (anag.)" , "couple linked" , "Two in a romantic relationship?" , "Separate article" , "Romantic couple" .)
