Persuade Italy's new leader (6)
I believe the answer is:
induce
'persuade' is the definition.
(I've seen this before)
'italy's new leader' is the wordplay.
'italy' becomes 'i'.
'new' becomes 'n'.
'leader' becomes 'duce' (Duce is an example**).
'i'+'n'+'duce'='INDUCE'
(Other definitions for induce that I've seen before include "Give rise to" , "Bring on by artificial means" , "Bring on, cause to happen" , "Persuade, hasten childbirth" , "Persuade or bring on, say birth" .)
