Ideal citizen displaying love for autocratic leader (8)
I believe the answer is:
notional
'ideal' is the definition.
(thesaurus)
I cannot understand how the rest of the clue works.
(Other definitions for notional that I've seen before include "La Gioconda" , "Assumed to be correct for particular purpose, say estimate" , "Hypothetical, speculative" , "Theoretic" , "Existing as theory, not existing in reality" .)
