Nobel Peace Prize winner Mandela (6)
I believe the answer is:
nelson
'nobel peace prize winner mandela' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for nelson that I've seen before include "English naval commander - wrestling hold" , "Admiral on a column" , "English admiral, lover of Lady Hamilton" , "Noted English admiral" , "Horatio - - , naval commander" .)
