MPs are elected from 13 five-seat constituencies by single transferable vote.[24] Candidates who pass the Hagenbach-Bischoff quota in the first round are elected, and any surplus votes transferred to the remaining candidates, who will be elected if this enables them to pass the quotient.[24] The lowest ranked candidates are then eliminated one-by-one with their preferences transferred to other candidates, who are elected as they pass the quotient, until all five seats are filled.[25] If a party wins a majority of first preference votes but fails to achieve a parliamentary majority, they are awarded seats to ensure a one-seat majority, if they are one of only two parties to obtain seats.[25] In 2018, the government of Malta lowered the national voting age to 16.[26] Due to the COVID-19 pandemic, arrangements were being made for drive-through voting.[27][28] Despite conducting elections under a proportional ranked preferential system, Malta has a stable two-party system, with only the Nationalist Party and Labour Party having a realistic chance of forming a government.[29][30] No coalition governments have been needed since 1953.
