Unruly skinhead to follow rioting as well (7)
I believe the answer is:
lawless
'unruly' is the definition.
(I've seen this before)
'skinhead to follow rioting as well' is the wordplay.
'skinhead' becomes 's' (head letter of 'skin').
'to follow' is a charade indicator (letters next to each other) (some letters go after or follow others).
'rioting' indicates an anagram (I've seen this in other clues).
'as'+'well'='aswell'
'aswell' with letters rearranged gives 'lawles'.
's' after 'lawles' is 'LAWLESS'.
(Other definitions for lawless that I've seen before include "Anarchic, without any controls" , "disobedient" , "Slew Sal for being criminal" , "Without rules" , "Ungoverned" .)
