The initial vote count had female candidates winning 33 seats in Iceland’s 63-seat parliament, the Althing, in an election that saw centrist parties make the biggest gains.

Hours later, a recount in western Iceland changed the outcome, leaving female candidates with 30 seats, a tally previously reached at Iceland’s second most recent election, in 2016. Still, at almost 48% of the total, that is the highest percentage for women lawmakers in Europe.

Only a handful of countries, none of them in Europe, have a majority of female lawmakers. According to the Inter-Parliamentary Union, Rwanda leads the world with women making up 61% of its Chamber of Deputies, with Cuba, Nicaragua and Mexico on or just over the 50% mark. Worldwide, the organization says just over a quarter of legislators are women.

“The female victory remains the big story of these elections,” politics professor Olafur Hardarson told broadcaster RUV after the recount.

Iceland’s voting system is divided into six regions and the recount in western Iceland was held after questions about the number of ballots cast. The mistakes have not been entirely explained but are thought to be due to human error.

The three parties in the outgoing coalition government led by Prime Minister Katrin Jakobsdottir won a total of 37 seats in Saturday’s vote, two more than in the last election, and appeared likely to continue in power.

Opinion polls had suggested a victory for left-leaning parties in the unpredictable election, which saw 10 parties competing for seats. But the center-right Independence Party took the largest share of votes, winning 16 seats, seven of them held by women. The centrist Progressive Party celebrated the biggest gain, winning 13 seats, five more than last time.

Before the election, the two parties formed Iceland’s three-party coalition government, together with Jakobsdottir’s Left Green Party. Her party lost several seats, but kept eight, outscoring poll predictions.

The three ruling parties haven’t announced whether they will work together for another term, but given the strong support from voters it appears likely. It will take days, if not weeks, for a new government to be formed and announced.

Climate change had ranked high on the election agenda in Iceland, a glacier-studded volcanic island nation of about 350,000 people in the North Atlantic. An exceptionally warm summer by Icelandic standards — with 59 days of temperatures above 20 C (68 F) — and shrinking glaciers have helped drive global warming up the political agenda.

But that didn’t appear to have translated into increased support for any of the four left-leaning parties that campaigned to cut carbon emissions by more than Iceland is committed to under the Paris Climate Agreement.

One candidate who saw her victory overturned by the recount was law student Lenya Run Karim, a 21-year-old daughter of Kurdish immigrants who ran for the anti-establishment Pirate Party.

“These were a good nine hours,” said Karim, who would have been Iceland’s youngest-ever lawmaker.
