Limitation as art reworked in autocratic approach (15)
I believe the answer is:
totalitarianism
'autocratic approach' is the definition.
(I've seen this in another clue)
'limitation as art reworked' is the wordplay.
'reworked' indicates anagramming the letters.
'limitation'+'as'+'art'='limitationasart'
'limitationasart' is an anagram of 'TOTALITARIANISM'.
'in' acts as a link.
(Other definitions for totalitarianism that I've seen before include "Dictatorship" , "Allowing no opposition" .)
