Latest run for paper (9)
I believe the answer is:
newsprint
'paper' is the definition.
(newsprint is a kind of paper)
'latest run' is the wordplay.
'latest' becomes 'new'.
'run' becomes 'sprint' (sprint is a kind of run**).
'new'+'sprint'='NEWSPRINT'
'for' is the link.
(Other definitions for newsprint that I've seen before include "cheap paper" , "Material for publication" , "Kind of paper this is produced on" , "FT for example" , "Paper for dailies" .)
