Manchester team claiming senior journalist is lacking refinement (8)
I believe the answer is:
unedited
'is lacking refinement' is the definition.
I can't tell whether this defines the answer.
'manchester team claiming senior journalist' is the wordplay.
'manchester team' becomes 'United' (Manchester United football club).
'claiming' indicates putting letters inside.
'senior journalist' becomes 'ed' (abbreviation for editor).
'united' enclosing 'ed' is 'UNEDITED'.
Can you help me to learn more?
(Other definitions for unedited that I've seen before include "Left as seen" , "As written, without correction" , "Not ready for publication" , "In the original version" , "Never before published" .)
