Reissued order to a fighter in the ring (8)
I believe the answer is:
toreador
'fighter in the ring' is the definition.
(bullfighter)
'reissued order to a' is the wordplay.
'reissued' is an anagram indicator.
'order'+'to'+'a'='ordertoa'
'ordertoa' anagrammed gives 'TOREADOR'.
(Other definitions for toreador that I've seen before include "One who fights bulls" , "Killer facing charges" , "Too drear for a bullfighter" , "one features in The Ring" , "Adore rot (anag)" .)
