Her Social Democratic Party Prime Minister Sana Marin it is recording nearly the same numbers as centre-right rival the conservative National Alliance party (NCP), led by former finance minister Petri Orpo, with the far-right trailing, according to partial results from today’s parliamentary elections in Finland.

After the votes are counted which were filed in advance, representing 40.1% of registered voters, the center-right Orpo party collects 20.8%, the Social Democrats of Marin 20.7%, while the far-right anti-immigrant Finns party 18.6%.

Marin, 37, has been Prime Minister of Finland since late 2019, head of a center-left coalition of five parties. The candidate of the party that comes out first traditionally takes the prime ministership in Finland—this unwritten rule has been followed without exception since 1987—provided they can secure a majority in parliament.

In each case, these elections are of particular interest as the three main candidates are fighting an ambiguous battle, while Finland is preparing in the coming days to write a new page in its history with its entry into NATO.

The country’s parliament has 200 seats. The formation of a government takes an average of six weeks.

Marin is expected to at least be nominated acting prime minister next week when Finland officially joins NATO, following the final necessary green light from Turkey on Thursday. The election result is not expected to affect this process, as all major parties are in favor of the country joining the NATO alliance.
