Riot Act laid out getting autocratic (11)
I believe the answer is:
dictatorial
'autocratic' is the definition.
('dictatorial' can be a synonym of 'autocratic')
'riot act laid out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'riot'+'act'+'laid'='riotactlaid'
'riotactlaid' with letters rearranged gives 'DICTATORIAL'.
'getting' acts as a link.
(Other definitions for dictatorial that I've seen before include "Overbearing" , "tyrannical" , "Given to telling others what to do" , "Autocratic" .)
