Famous, but wrong about Tory leader (8)
I believe the answer is:
immortal
'famous' is the definition.
(thesaurus)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for immortal that I've seen before include "never to be forgotten" , "Never dying" , "Living for ever" , "Enduring" , "Everlasting" .)
