Artists young reporters will entertain first (7)
I believe the answer is:
cubists
'artists' is the definition.
(cubist is a kind of artist)
'young reporters will entertain first' is the wordplay.
'young reporters' becomes 'cubs' (I've seen this in another clue).
'will entertain' indicates putting letters inside (entertain can mean to host or welcome in).
'first' becomes 'ist' (ist resembles 1st).
'cubs' going around 'ist' is 'CUBISTS'.
(Other definitions for cubists that I've seen before include "group of artists" , "Painters" , "Disciples of Picasso, perhaps" .)
