Parallel voting is a type of mixed electoral system in which representatives are voted into a single chamber using two or more different systems, most often first-past-the-post voting (FPTP) with party-list proportional representation (PR). It is the most common form of mixed member majoritarian representation (MMM), which is why these terms are often used synonymously with each other. In some countries, parallel voting is known as the supplementary member (SM) system, while in academic literature it is sometimes called the superposition method within mixed systems.
The Chamber of Deputies is the lower house of the bicameral Italian Parliament, the upper house being the Senate of the Republic. The two houses together form a perfect bicameral system, meaning they perform identical functions, but do so separately. The Chamber of Deputies has 400 seats, of which 392 will be elected from Italian constituencies, and 8 from Italian citizens living abroad. Deputies are styled The Honourable and meet at Palazzo Montecitorio.

The 1987 Italian general election was held in Italy on 14–15 June 1987. This election was the first Italian election in which the distance between the Christian Democrats and the Communists grew significantly instead of decreasing. Two parties that had not previously been in parliament won representation: the Greens with thirteen seats, and the Northern League with two.
A majoritarian electoral system is an electoral system where the candidates or parties with the most votes takes all seats using the winner-takes-all principle and in this way provides majoritarian representation. However, there are many electoral systems considered majoritarian based on different definitions, including types of at-large majoritarian representation such as block voting or party block voting, but district-based majoritarian systems such as first-past-the-post voting (FPTP/SMP). Where two candidates are in the running, the one with the most votes will have a majority, but where there are three or more candidates, it often happens that no candidate takes a majority of the votes.

A mixed electoral system or mixed-member electoral system combines methods of majoritarian and proportional representation (PR). The majoritarian component is usually first-past-the-post voting (FPTP/SMP), whereas the proportional component is most often based on party-list PR. The results of the combination may be mixed-member proportional (MMP), where the overall results of the elections are proportional, or mixed-member majoritarian, in which case the overall results are semi-proportional, retaining disproportionalities from the majoritarian component.
The Italian electoral law of 2017, colloquially known by the nickname Rosatellum bis or simply Rosatellum after Ettore Rosato, the Democratic Party (PD) leader in the Chamber of Deputies who first proposed the new law, is a parallel voting system, which acts as a mixed electoral system, with 37% of seats allocated using a first-past-the-post electoral system and 63% using a proportional method, with one round of voting. The Chamber and Senate of the Republic did not differ in the way they allocated the proportional seats, both using the largest remainder method of allocating seats.

Mixed member majoritarian representation (MMM) is type of a mixed electoral system combining majoritarian and proportional methods, where the disproportional results of district contests using a plurality voting system or other, usually first-past-the-post voting, are completely separate from the proportional component. Mixed member majoritarian systems are therefore described as semi-proportional representation, and are usually contrasted with mixed-member proportional representation (MMP) which aims to provide proportional representation via additional compensation ("top-up") seats.
The next Italian general election will occur no later than 22 December 2027, although it may be called earlier as a snap election.
