News of Hollywood trial? (6)
I believe the answer is:
latest
'news' is the definition.
(the latest means the latest news)
'hollywood trial?' is the wordplay.
'hollywood' becomes 'LA' (Hollywood is a neighbourhood of Los Angeles).
'trial?' becomes 'test' ('test' can be a synonym of 'trial').
'la'+'test'='LATEST'
'of' acts as a link.
(Other definitions for latest that I've seen before include "News update" , "State-of-the-art" , "hot bit of news" , "Current" , "Most recent or most unpunctual" .)
