Issue ID to suspect revolutionary (9)
I believe the answer is:
seditious
'revolutionary' is the definition.
(I've seen this before)
'issue id to suspect' is the wordplay.
'suspect' is an anagram indicator (a suspicious or unusual spelling).
'issue'+'id'+'to'='issueidto'
'issueidto' with letters rearranged gives 'SEDITIOUS'.
(Other definitions for seditious that I've seen before include "Subversive" , "Rabble-rousing" , "Inciting to revolt" , "Revolutionary" , "undermining the state" .)
