Many countries broadcast fake news of dictator's crushing victory (9)
I believe the answer is:
landslide
'victory' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for landslide that I've seen before include "Massive election win" , "convincing victory" , "Runaway" , "easy victory" , "Overwhelming victory in election, or a natural disaster" .)
