Agent twisted more awkwardly around ruler (7)
I believe the answer is:
emperor
'ruler' is the definition.
(I know that emperor is a type of emperor)
'agent twisted more awkwardly around' is the wordplay.
'agent' becomes 'rep' (short for representative).
'twisted' is a reversal indicator.
'awkwardly' indicates anagramming the letters.
'around' means one lot of letters goes inside another.
'rep' reversed gives 'per'.
'more' anagrammed gives 'emor'.
'per' inserted inside 'emor' is 'EMPEROR'.
(Other definitions for emperor that I've seen before include "Character in 24 ac" , "Title of sovereignty" , "Ancient Roman ruler" , "Supreme ruler" , "Eg, Caesar" .)
