Help official put about 'fake news' (6)
I believe the answer is:
relief
'help' is the definition.
(relief is a kind of help)
'official put about fake news' is the wordplay.
'official put' becomes 'ref' (I am not sure about this - if you are sure you should believe this answer much more).
'about' is an insertion indicator.
'fake news' becomes 'lie'.
'ref' going around 'lie' is 'RELIEF'.
Can you help me to learn more?
(Other definitions for relief that I've seen before include "Cosmos" , "That's a load off my mind" , "Easement or assistance to people in need" , "Break" , "Sort of map" .)
