Leader needs trip abroad (9)
I believe the answer is:
president
'leader' is the definition.
(president is a kind of leader)
'needs trip abroad' is the wordplay.
'abroad' indicates an anagram.
'needs'+'trip'='needstrip'
'needstrip' with letters rearranged gives 'PRESIDENT'.
(Other definitions for president that I've seen before include "Cleveland?" , "Country's leader" , "The elected head of a republic" , "authority figure" , "Celebrant" .)
