REYKJAVIK, April 4 — Iceland Prime Minister Sigmundur David Gunnlaugsson faces a no confidence vote in parliament amid revelations he and his wife had an investment account in the British Virgin Islands created with the aid of the Panama-based law firm at the center of a global tax evasion leak.

The opposition has called for a vote against the government as parliament begins its session at 3pm local time. Protests are scheduled in Reykjavik starting two hours later.

“I hope that Sigmundur David realises the seriousness of this matter and has the decency to resign before parliament convenes today,” Birgitta Jonsdottir, a lawmaker for the Pirate Party, said on her Facebook page today. A March MMR poll showed that the political group is now Iceland’s biggest with 37 per cent of voters backing it, compared with 36.2 per cent for the ruling coalition of Independence and Progressive Parties that Gunnlaugsson leads.

Gunnlaugsson, who started his four-year term in 2013, finds himself in the middle of a political storm after it was revealed in a leak uncovered by the International Consortium of Investigative Journalists, or ICIJ, that he and his wife had an offshore account to manage an inheritance. His wife, Anna Sigurlaug Palsdottir, previously revealed the account in a Facebook posting in March after the premier was questioned about the money.

“It’s been clear since before I began participating in politics that my wife had a considerable amount of money,” Gunnlaugsson wrote on his website. “Some people find that in itself very negative. I can’t do much about that because I’m neither going to divorce my wife nor demand that she relinquish her family inheritance.”

According to the ICIJ report, Palsdottir says she has always paid all her taxes owed on the Wintris account, which was confirmed by her tax firm, KPMG. ICIJ cited a leak covering documents spanning leaders and businesses across the globe from 1977 to 2015 from Panama-based law firm Mossack Fonseca, a top creator of shell companies that has branches in Hong Kong, Miami, Zurich and more than 35 other places around the world.

“As has been explained publicly, in establishing this company, the Prime Minister and his wife have adhered to Icelandic law, including declaring all assets, securities and income in Icelandic tax returns since 2008,” a Gunnlaugsson spokesman said in a statement to the ICIJ.

The premier was one of 12 current and former world leaders to have offshore holdings revealed in the leak that has come to be called the Panama Papers. Offshore holdings can be legal, though documents show some banks and law firms failed to follow requirements to check their clients are not involved in crimes. — Bloomberg
