News interrupting unusually dire television service (6,3)
I believe the answer is:
dinner set
'service' is the definition.
(dinner set is a kind of service)
'news interrupting unusually dire television' is the wordplay.
'news' becomes 'nn' (I've seen this in other clues**).
'interrupting' means one lot of letters goes inside another.
'unusually' indicates anagramming the letters.
'television' becomes 'set' (I've seen this in other clues).
'dire' anagrammed gives 'dier'.
'nn' put within 'dier' is 'dinner'.
'dinner'+'set'='DINNER-SET'
(Other definitions for dinner set that I've seen before include "Collection of plates and dishes" , "China" , "Plates etc" , "might be taken out for a meal" , "Table service" .)
