Country yours truly led (4)
I believe the answer is:
iran
'country' is the definition.
(Iran is an example)
'yours truly led' is the wordplay.
'yours truly' becomes 'i'.
'led' becomes 'ran' ('run' can be a synonym of 'lead').
'i'+'ran'='IRAN'
(Other definitions for iran that I've seen before include "Former Persia" , "Middle Eastern country" , "Persia today" , "Country where the official language is Farsi" , "oil supplier" .)
