In Tirana the mayor detested person (8)
I believe the answer is:
anathema
'detested person' is the definition.
(I've seen this before)
'in tirana the mayor' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ANATHEMA' is hidden within 'tirana the mayor'.
(Other definitions for anathema that I've seen before include "Person or thing that's abhorred" , "Object of detestation" , "Condemned or excommunicated by church" , "odious" , "Formal curse leading to excommunication" .)
