He breached security protocol by not informing the government of his travels
Iran trip costs Norway fisheries minister his job
Norway's fisheries minister has resigned after admitting to breaching government protocol by visiting Iran for a holiday last month without informing colleagues of his whereabouts.
Per Sandberg, a right-wing figure in the Scandinavian country, was condemned by the country's Prime Minister Erna Solberg for failing to adhere to the cabinet's rules about foreign travel.
The minister took a government-issued mobile device with him to the Islamic Republic, a state known for intense surveillance of foreign figures.
The 58-year-old is the deputy head of the anti-immigration Progress Party, which advocates for the swift deportation of migrants who fail in their application to enter Norway.
He has subsequently faced censure from within his own party for the trip with his Iranian-born girlfriend, 28-year-old Bahareh Letnes, who secured Norwegian residency over a decade ago. She had her asylum request rejected three times in Norway and was expelled, but finally obtained a residency permit on the grounds that she risked being subjected to a forced marriage in Iran.
Ms Solberg had ordered Mr Sandberg to hand his phone to Norwegian for checks, fearing that Iran had breached his phone and communications.
The Norwegian leader and her ruling minority party have faced criticism for their handling of national security, or perceived lack of it.
Editorial: Iran sanctions must be part of a wider plan
Norway's intelligence agency regularly lists Iran as one of the countries most likely to carry out espionage, alongside China and Russia.
"Per himself asked to step down, and I think it was the right decision," Conservative Prime Minister Erna Solberg told reporters.
"He didn't show the necessary common sense when it comes to handling security issues," she said.
Mr Sandberg issued an apology in a bid to quell the criticism, but with new details emerging daily he ultimately decided to resign.
Among other things, it emerged he had also broken security protocol in May when he took his work phone to China.
"It's sad," he told reporters on Monday. "I had hoped to finish up a few projects," he added, refusing to comment on the personal aspects of the affair.
Norwegian intelligence services have opened a probe into Letnes, who denies any ties to the Iranian regime.
Sandberg will be replaced by Harald Tom Nesvik, a member of his own party, and has also stepped down as deputy head of the party.
