At a national level, Greece holds elections for its legislature, the Hellenic Parliament. Election of the legislature The Greek Parliament (Voulí ton Ellínon) has 300 members, elected for a four-year term by a system of 'reinforced' proportional representation. Of the 300 seats, 285 are allocated to 59 constituencies, 50 of which are multi-seat and 9 single-seat. The remaining 15 MPs are elected from nationwide party lists, of which 3 are required to represent the Greek diaspora. Seat allocation to individual parties is done on the basis of their nationwide vote share, provided they have reached the electoral threshold of 3%. In each constituency, voters may select the candidate or candidates of their choice by marking their name on the party ballot. In 2016, the previous parliament, under a left-wing majority, abolished the reinforced proportionality system, which had been in effect since 2004. The previous system had been boosting the first party's seat count with 50 "bonus" seats, in order to facilitate single-party absolute majorities in parliament. It was replaced by a party-list proportional representation system, under which single-party parliamentary majorities, commonly achieved by first parties under previous electoral systems, could now only be achieved with a vote share of at least 45%, effectively making coalition governments the norm. On those grounds, and arguing that proportional representation would cause political instability, the new law was strongly contested by the conservative opposition and failed to get the two thirds supermajority required by the constitution for a new electoral system to be immediately applied in the next election. Hence, the previous system was still applied in the 2019 election, which the opposition won, whereas the new system will be applied in the next election for the first time. In 2020, parliament, under its new conservative majority, repealed party-list proportional representation and reverted the system to a sliding scale majority bonus system. The new system is similar to the pre-2016 reinforced majority system, with the only difference that the size of the majority bonus is now tied to the largest party's national vote share, ranging from a minimum of 20 seats for a vote share of 25% to a maximum of 50 seats for vote shares of 40% and above; no majority bonus is awarded to the first party if its vote share is below 25%. Under normal circumstances, an absolute majority can be achieved by the first party with 38% of the vote.
