HELSINKI, Finland — President Sauli Niinisto of Finland was elected to a second six-year term on Sunday, avoiding a second-round runoff by capturing over 60 percent of the vote.

The famously low-key president was initially cautious as the results flashed up on a vast screen at his election reception in downtown Helsinki. The night, he warned, could still “bring surprises.”

But in the end the results were as predicted — what Mika Aaltola of the Finnish Institute of International Affairs described as “surprisingly unsurprising results in an age of democratic vulnerabilities.”

The far-right candidate, Laura Huhtasaari, a creationist populist inspired by President Trump, also declared victory, despite securing just over 6 percent of the vote.
