Fleet Street jargon — a June loser (anag) (10)

I believe the answer is:

journalese

(Other definitions for journalese that I've seen before include "in style of 11 [PRESS RELEASE] ?" , "Hacks may use this" , "Hack jargon" , "Hack's work" , "Hackneyed style in certain newspapers" .)

I've seen this clue in The Guardian.
