Different roles. in theory, the president is more powerful, signs bills into laws, but practically speaking, has more of a representative and ceremonial role.Facial structure looks Italian... So I guess Italian PM....but he is actually Italian President Sergio Mattarella. Don't know who is more powerful, PM or President in Italy.
pm is the head of government and is the one voted by the people
current ones are very pro-west (understandably so)
