Finns today are expected to re-elect the charismatic and cautious president Sauli Niinisto to navigate their country across an increasingly tense political landscape between the West and their powerful neighbour Russia.
Finland's most popular president in more than three decades, the 69-year-old who campaigned as an independent has skillfully shifted the EU member state closer to NATO without antagonising Russia, with whom the Nordic country shares the longest border in the bloc.
Finns "want stability and don't want change right now," Juhana Aunesluoma, research director at the University of Helsinki Network for European Studies, told AFP.
The latest opinion polls credit Niinisto with between 51 and 63 percent of votes, losing ground but still far ahead of the seven other candidates. His main rival, Pekka Haavisto of the Green party, is seen garnering around 13-14 percent support.
Polling stations are to open at 0700 GMT and close at 1800 GMT today. Niinisto has already cast his vote along with more than 36 percent of Finland's 3.5 million registered voters.
If he is elected for another six-year term with at least 50 percent of votes in today's first round, it would be a first since Finland introduced a two-round presidential election by popular vote in 1994.
If no candidate gets 50 percent, then the second round of voting will be held on February 11.
As Finland's head of state and supreme commander of the armed forces, the president shares responsibility with the government for defence and foreign policy, though not EU affairs.
During his first term, Niinisto meticulously cultivated ties with Russian President Vladimir Putin, who has been at odds with the West since Russia's 2014 annexation of Crimea.
The two leaders played an ice hockey match in 2012 and attended an opera together last year as part of Finland's 100th anniversary of independence after the fall of the Tsarist Russian empire.
"Niinisto's strategies and tactics have been rather successful, especially handling Putin," Aunesluoma said.
"People get the sense that he has the capacity and tools to cope with the challenges."
At the same time, however, Finland, a Russian Grand Duchy from 1809 to 1917, has forged increasingly close ties with the United States and NATO, of which it is not a member, unlike the Baltic states.
Russia has repeatedly warned Sweden and Finland against joining NATO, an issue regularly debated in the two Nordic countries, perceiving it as a provocation or even a justification for war.
"One of the central goals of Finland's foreign and security policy is to avoid getting pulled into an armed conflict," Niinisto told Finnish defence forces in a speech earlier this month.
Teivo Teivainen, professor of world politics at the University of Helsinki, said Niinisto's "ambiguity" on NATO membership "was a successful strategy" during the election campaign as he has not disgruntled voters who are either for or against joining the alliance.
Russian military activity in the region has increased in recent years, including several violations of Finnish airspace and warplanes allegedly flying with switched-off transponders -- devices that allow radars to identify aircraft.
Finnish and Russian defence officials announced last year that they would set up a 24-hour hotline to avoid any "misunderstandings".
Born into a working-class family in the southwestern Finnish town of Salo in August 1948, Niinisto -- the youngest of four children -- became a lawyer before entering politics as a member of the conservative National Coalition Party.
He served as justice minister in 1995-1996, before taking over the finance portfolio until 2003.
An advocate of budgetary discipline, Niinisto helped pull Finland out of a deep recession in the 1990s and into the eurozone.
Highly-publicised relationships and a life scarred by tragedy have given Niinisto a human image among Finns.
The father of two sons lost his first wife in a car accident in 1995 and narrowly survived the 2004 tsunami in Thailand by climbing a tree with his youngest child.
Following a high-profile affair with a former beauty queen-turned-MP, the couple got engaged in 2003 but broke up the following year.
He married his second wife, the Finnish poet Jenni Haukio -- 29 years his junior -- in 2009. The couple announced in October they were expecting a child in February, hitting a soft spot among voters.
