History Turku and Pori Province South was one 16 electoral districts established by the Election Act of the Grand Duchy of Finland (Suomen Suuriruhtinaanmaan Vaalilaki) passed by the Diet of Finland in 1906. It consisted of the hundreds (kihlakunta) of Åland, Halikko, Masku, Mynämäki, Piikkiö and Vehmaa in the province of Turku and Pori. The Åland region was separated into its own electoral district in 1947. At the same time, the town of Loimaa and the municipalities of Alastaro, Loimaa, Mellilä and Metsämaa were transferred from Turku Province North to Turku Province South. Somero municipality was transferred from Häme South to Turku South in 1990. The district was renamed Varsinais-Suomi in 1997. Kodisjoki municipality was transferred from Varsinais-Suomi to Satakunta in 1998.

Electoral system Varsinais-Suomi currently elects 17 of the 200 members of the Parliament of Finland using the open party-list proportional representation electoral system. Parties may form electoral alliances with each other to pool their votes and increase their chances of winning seats. However, the number of candidates nominated by an electoral alliance may not exceed the maximum number of candidates that a single party may nominate. Seats are allocated using the D'Hondt method.
