Tyrant adroit manoeuvring around court (8)
I believe the answer is:
dictator
'tyrant' is the definition.
(I've seen this before)
'adroit manoeuvring around court' is the wordplay.
'manoeuvring' indicates an anagram.
'around' indicates putting letters inside.
'court' becomes 'ct' (abbreviation used in road names).
'adroit' anagrammed gives 'diator'.
'diator' placed around 'ct' is 'DICTATOR'.
(Other definitions for dictator that I've seen before include "Extraordinary old magistrate" , "Authoritarian, tyrant" , "Absolute ruler (Great in Chaplin film)" , "ruthless leader" , "Such as Saddam Hussein" .)
