147 deputies (members of the Chamber of Deputies) and 74 senators (members of the Senate of the Republic) are elected in single-member constituencies and the rest from party lists. (In addition, there are also several so-called "senators for life". These include former Italian presidents and people appointed by presidential decree in recognition of special service to the country.)[1]
