Rabble-rousing shunning leader in newspaper issue (7)
I believe the answer is:
edition
'newspaper issue' is the definition.
(I've seen this before)
'rabble-rousing shunning leader' is the wordplay.
'rabble-rousing' becomes 'sedition' (rabble-rousing means stirring revolution).
'shunning leader' means to remove the first letter.
'sedition' with its initial letter taken off is 'EDITION'.
'in' acts as a link.
(Other definitions for edition that I've seen before include "Copies of book printed from one set of type" , "copy of work" , "Particular version of a book, etc" , "single programme" , "in printed form" .)
