Newsworthy drama involving Greek island (5)
I believe the answer is:
hydra
'greek island' is the definition.
(I've seen this before)
'newsworthy drama involving' is the wordplay.
'involving' indicates the answer is hidden within the clue (I've seen 'involves' mean this).
'HYDRA' is hidden within 'newsworthy drama'.
(Other definitions for hydra that I've seen before include "M any-headed monster fought by Hercules" , "Many-headed serpent" , "Persistent trouble" , "Nine-headed monster killed by Hercules" , "Small red-berried tree" .)
