Explosive piece of journalism (6)
I believe the answer is:
report
'explosive piece' is the definition.
'report' can be an answer for 'piece' (thesaurus). I'm unsure of the 'explosive' bit.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for report that I've seen before include "Sudden noise; account of progress" , "A crack" , "Work for a newspaper" , "A loud bang, or an account" , "Complain about - account" .)
