Issue subversive speech with no introduction (7)
I believe the answer is:
edition
'issue' is the definition.
(I know that edition is a type of issue)
'subversive speech with no introduction' is the wordplay.
'subversive speech' becomes 'sedition'.
'with no introduction' means to remove the first letter.
'sedition' with its initial letter removed is 'EDITION'.
(Other definitions for edition that I've seen before include "Particular version of a book, etc" , "I die not (anag)" , "Copies of book printed from one set of type" , "in printed form" , "Volume" .)
