Issues about sedition (8)
I believe the answer is:
editions
'issues' is the definition.
(edition is a kind of issue)
'about sedition' is the wordplay.
'about' indicates anagramming the letters.
'sedition' with letters rearranged gives 'EDITIONS'.
(Other definitions for editions that I've seen before include "Numbers" , "written publications?" , "Book published at different times" , "Impressions given!" , "Particular forms of published texts" .)
