Bringer of news speaks again, wasting little time (7)
I believe the answer is:
reuters
'bringer of news' is the definition.
(news organisation)
'speaks again wasting little time' is the wordplay.
'speaks again' becomes 'reutters' (utters again).
'wasting' suggests deleting specific letters.
'little time' becomes 't' (abbreviation for time).
'reutters' with 't' taken out is 'REUTERS'.
(Other definitions for reuters that I've seen before include "International news agency" , "Noted news agency" , "up-to-date agency" .)
