Presidents of Italy "for outstanding merits in the social, scientific, artistic or literary field". The current life senators are: The current term of the Senate is five years, except for senators for life that hold their office for their lifetime. Until a Constitutional change on 9 February 1963, the Senate was elected for six-year terms. The Senate may be dissolved before the expiration of its normal term by the president of the Republic (e.g. when no government can obtain a majority). Electoral system and election of the Senate According to article 58 of the Italian constitution, Italian citizens aged 18 onwards (until 2021 25 years) are enabled to vote for the Senate. The electoral system is a parallel voting system, with 37% of seats allocated using first-past-the-post voting (FPTP) and 63% using proportional representation, allocated with the largest remainder method, with one round of voting. The 200 elected senators are elected in: 74 in single-member constituencies, by plurality; 122 in multi-member constituencies, by regional proportional representation; 4 in multi-member abroad constituencies, by constituency proportional representation. For Italian residents, each house members are elected by single ballots, including the constituency candidate and his/her supporting party lists. In each single-member constituency the deputy/senator is elected on a plurality basis, while the seats in multi-member constituencies will be allocated nationally. In order to be calculated in single-member constituency results, parties need to obtain at least 1% of the national vote. In order to receive seats in multi-member constituencies, parties need to obtain at least 3% of the national vote. Elects from multi-member constituencies will come from closed lists. The single voting paper, containing both first-past-the-post candidates and the party lists, shows the names of the candidates to single-member constituencies and, in close conjunction with them, the symbols of the linked lists for the proportional part, each one with a list of the relative candidates. The voter can cast their vote in three different ways: Drawing a sign on the symbol of a list: in this case the vote extends to the candidate in the single-member constituency which is supported by that list. Drawing a sign on the name of the candidate of the single-member constituency and another one on the symbol of one list that supports them: the result is the same as that described above; it is not allowed, under penalty of annulment, the panachage, so the voter can not vote simultaneously
