Article with no charm upset newsreader (9)
I believe the answer is:
anchorman
'newsreader' is the definition.
'article with no charm upset' is the wordplay.
'article' becomes 'an' (indefinite article).
'with' means one lot of letters goes inside another.
'upset' is an anagram indicator.
'no'+'charm'='nocharm'
'nocharm' with letters rearranged gives 'nchorma'.
'an' going around 'nchorma' is 'ANCHORMAN'.
(Other definitions for anchorman that I've seen before include "with weight on board?" , "One broadcasting" , "Crucial participant" , "Last runner in a relay race - person presenting a TV show" , "Maybe last person to run" .)
