Polls opened across Sweden on Sunday in an election that has been described as one of the closest in recent memory. The centre-left opposition alliance, led by the Social Democrats' Magdalena Andersson, holds a narrow lead in the final polls — just 0.3 percentage points ahead of the right-wing bloc. But that gap has narrowed considerably in the final days of the campaign, leaving the outcome uncertain.
At stake are issues of migration, crime, and the economy, with Sweden's reputation as a global champion of human rights also said to be on the line. The far-right Sweden Democrats, who have long been on the fringes of Swedish politics, could now enter government for the first time if the right-wing parties can form a coalition or secure enough support.
Andersson is regarded as the favourite to become prime minister again after four years in opposition, but a right-wing victory would hand power to a bloc that includes the Moderates, Christian Democrats, and Liberals, with the Sweden Democrats as a key supporting force.
Voter turnout is expected to be high, and results are likely to come in over the course of Sunday evening and Monday.
