HELSINKI (AP) — Finland holds local elections Sunday in a first litmus test for popular young Social Democratic Prime Minister Sanna Marin, who took office 18 months ago shortly before the pandemic outbreak, and whose party is behind in polls across the country.

The 35-year-old Marin, who became Europe’s youngest government leader in December 2019, enjoys high personal popularity and has won international praise for her handling of the COVID-19 crisis in the Nordic nation of 5.5 million.

However, the result of Sunday's municipal elections — the first for Marin as leader of both the government and the Social Democratic Party — may be a disappointment to her.

Despite her popularity, the Social Democrats have failed to attract young voters in particular. Two opposition parties, the conservative National Coalition Party and the populist Finns Party, are in the lead in the polls.

The vote to renew local councils in Finland’s more than 300 municipalities is seen as a catalyst for parties’ popularity ahead of the 2023 parliamentary election. Stakes are higher this time because the elections were postponed for two months due to COVID-19, and because of the tensions inside Marin’s center-left, five-party governing coalition.

In April, it came near collapse because a senior coalition member — the Center Party — threatened to leave the government in a dispute over spending. Only persistent negotiations saved Marin's Cabinet from collapsing but political analysts said scars and ideological differences are running deep between the Social Democrats and the centrists.

The main themes dominating the local election are the government’s planned social and health care reform in municipalities, taxation and the implications of Finland’s COVID-19 exit strategy.

Since the start of the pandemic, Finland has recorded just under 94,000 cases with 964 deaths, which are among the lowest figures in Europe. An improved situation means Marin's government has been able to ease some restrictions and the country is reopening.

Marin, whose political career started in the southern industrial and university city of Tampere, said Friday she had received her first COVID-19 jab.

In a Twitter post with a photo showing a band-aid on her left shoulder, Marin said: “Got first corona vaccine shot. Summer is here. Sun is shining.”

In Helsinki, the capital, the most acute question is who should become the next mayor of the city of 630,000. The conservatives are trying to stay in power — which they have held for decades — while the Greens are closing in, followed by Marin’s Social Democrats.

A poll commissioned by Finnish public broadcaster YLE predicted Thursday that, nationwide, the National Coalition Party would garner some 19.6% of votes, the Finns Party 18% and the Social Democrats 17%, which is 1.1 percentage points lower than in the previous elections.

A third of eligible voters, or some 1.5 million people, had already voted in advance by the Tuesday deadline.
