HELSINKI -- Finns will be voting Sunday to fill the country's 200-seat Eduskunta parliament after a campaign that saw debates over the country's generous welfare model, its rapidly aging population and how far to go to fight climate change.
Here's a look at the key issues and the main players in the election:
JUST THE FACTS
Some 4.5 million people are eligible to vote in Sunday's parliamentary election in Finland and will be choosing between 19 political parties and movements.
Early voting is popular. Over 1.5 million people, or 36% of eligible voters, have already cast their ballots in advance. The results of that early vote will be published as soon the polls have closed Sunday at 1700 GMT (1 p.m. EDT), and fuller preliminary results are expected a few hours later.
CLIMATE CHANGE TENSIONS
Tackling climate change is a priority in a Nordic country that has one-third of its territory above the Arctic Circle, but there are clear tensions over what path to choose.
Finland is boosting its nuclear energy production by launching a new plant next year and lawmakers last month voted to completely phase out burning coal by 2029. Many parties back actions to fight global warming, include boosting the number of electric vehicles, cutting meat consumption through taxes or switching to more vegetarian food in public places like schools.
The populist Finns Party, however, has broadened its support by appealing to those who reject such sacrifices in the name of climate change.
QUALITY OF LIFE AND OTHER ELECTION TOPICS
Finnish voters have also been debating how best to preserve the country's health and social system, which for years has topped global quality-of-life and happiness rankings and created a world-renowned education system.
There are some divisions over proposed reforms, which are getting more urgent since the country's population of 5.5 million is rapidly aging. One plan aims to improve efficiency and reduce public spending by offering Finnish municipalities more freedom to choose between public and private providers for social needs and health care.
FINLAND'S MAIN CONTENDERS
Finland's center-left Social Democratic Party tops a recent poll with 19% support, according to a poll this week commissioned by Finnish public broadcaster YLE. The party would still need to find coalition partners if it ended up trying to form the next government.
Led by Antti Rinne, a former finance minister, the Social Democrats plan to raise taxes and increase spending to preserve a welfare system that is under huge strain. The party has also vowed to continue the country's pro-European Union stance.
Other key parties include the populist Finns Party led by Jussi Halla-aho, which is focusing on voters angry at urban global elites, and the National Coalition Party led by Petteri Orpo. Those parties took second and third places in the poll with 16.3% and 15.9% support, respectively. They are trailed by the Center Party and the Greens, who have strong urban support and back moves to fight climate change.
Finland's outgoing center-right coalition government, led by Prime Minister Juha Sipila of the Center Party, pushed through an austerity package that has helped Finland return to growth after a three-year recession.
FINLAND'S OTHER BIG POLITICAL JOB
Finland will take over the rotating six-month presidency of the European Union on July 1.
