Latest lie broadcast from the moon, say (9)
I believe the answer is:
satellite
'the moon say' is the definition.
(moon is a kind of satellite)
'latest lie broadcast' is the wordplay.
'broadcast' is an anagram indicator.
'latest'+'lie'='latestlie'
'latestlie' anagrammed gives 'SATELLITE'.
'from' is the link.
(Other definitions for satellite that I've seen before include "Country dependent on another" , "Heavenly body revolving around a planet" , "Body in orbit around another" , "Body that revolves around or serves another" , "important person's attendant" .)
