Resolve to free Teddy (9)
I believe the answer is:
roosevelt
'teddy' is the definition.
(I've seen this before)
'resolve to free' is the wordplay.
'free' indicates anagramming the letters.
'resolve'+'to'='resolveto'
'resolveto' is an anagram of 'ROOSEVELT'.
(Other definitions for roosevelt that I've seen before include "Name of two twentieth century US presidents" , "former president" , "Long-term leader" , "One of two US presidents" , "32nd US president, Franklin" .)
