Justice Minister Anna-Maja Henriksson will seek another term as leader of the Swedish People's Party (SPP).
Henriksson said on Saturday that she would seek re-election at a party congress next month. She has led the centrist party since 2016. She faces no leadership challenge.
The SPP elects its chair and leadership for a year at a time. The party congress is to be held virtually on 29-30 May.
"The SPP will continue to be the party for everyone who cares about a bilingual Finland, liberal Western democracy, human rights and Nordic co-operation. We are the liberal, non-socialist alternative with a great social conscience," she said in a statement.
Henriksson said she wants to see the SPP grow as a party, pledging that it will earn more than five percent of seats in June's local elections.
The latest Yle poll showed the SPP support unchanged at 4.3 percent, by far the lowest among the five government parties.
The party primarily defends the interests of Finland's Swedish-speaking minority, which has been dwindling since the country gained independence. It fell below 10 percent in the 1930s and below six percent in the 1980s.
As of the end of 2019, native Swedish speakers made up 5.2 percent of the population – a share that was exceeded by speakers of foreign languages in the mid-2010s.
