News from city trial (6)
I believe the answer is:
latest
'news' is the definition.
(the latest means the latest news)
'city trial' is the wordplay.
'city' becomes 'LA' (Los Angeles).
'trial' becomes 'test' (synonyms).
'la'+'test'='LATEST'
'from' acts as a link.
(Other definitions for latest that I've seen before include "State-of-the-art" , "Stop press news?" , "Most up-to-date" , "coming after all the others" , "Current" .)
