Next Finnish parliamentary election

The next parliamentary elections will be held in Finland in April 2023, or earlier if Parliament is dissolved ahead of schedule.
Electoral system.
The 200 members of the Eduskunta were elected using open list proportional representation in 13 multi-member constituencies, with seats allocated according to the D'Hondt method. The number of elected representatives is proportional to the population in the district six months prior to the elections. Åland has single member electoral district and its own party system.
Background.
The former prime minister, Antti Rinne, resigned from his post due to a scandal regarding the Finnish Postal Service (Posti). Rinne's Social Democratic Party of Finland elected a 34-year-old MP from the province of Pirkanmaa, Sanna Marin, to replace him. Marin took office on 10 December 2019. 
Covid-19's affect to the Finnish political system.
During the COVID-19 pandemic in Finland, the Social Democratic Party of Prime Minister Sanna Marin initially saw a sharp rise in popularity, and the Finns Party, leading polls before the pandemic, conversely saw a dip. By April 2021, the Finns Party have resurged, having overtaken the Social Democrats in polls and placed first in all representative polls conducted in 2021.
