Nonsense English idiot backed in news report (8)
I believe the answer is:
bulletin
'news report' is the definition.
(bulletin is a kind of news report)
'nonsense english idiot backed' is the wordplay.
'nonsense' becomes 'bull' (I've seen this before).
'english' becomes 'E' (abbreviation).
'idiot' becomes 'nit' (nit can mean a stupid person).
'backed' says the letters should be written in reverse.
'nit' written backwards gives 'tin'.
'bull'+'e'+'tin'='BULLETIN'
'in' acts as a link.
(Other definitions for bulletin that I've seen before include "Short statement on the news as it happens" , "News programme" , "Newsflash" , "News flash" , "Report for publication or broadcast" .)
