As a despot I sin, somehow showing no emotion (13)

I believe the answer is:

dispassionate

'showing no emotion' is the definition.

'as a despot i sin somehow' is the wordplay.
'somehow' indicates an anagram.
'as'+'a'+'despot'+'i'+'sin'='asadespotisin'
'asadespotisin' is an anagram of 'DISPASSIONATE'.

(Other definitions for dispassionate that I've seen before include "Rational, impartial" , "Not affected by personal feelings" , "Imperturbable" , "taking the unbiased view?" , "Objective, unemotional" .)

I've seen this clue in The Times.
