Lie uncontrollably with blunt report (8)
I believe the answer is:
bulletin
'report' is the definition.
(I know that bulletin is a type of report)
'lie uncontrollably with blunt' is the wordplay.
'uncontrollably with' indicates anagramming the letters (I've seen this in other clues).
'lie' mixed up with 'blunt' makes 'BULLETIN'.
(Other definitions for bulletin that I've seen before include "Blue lint (anag.)" , "Regular report" , "Blunt lie in offical news statement" , "News flash" , "Newsflash" .)
