This is stated by the party's foreign policy spokesperson Håkan Svenneling to Sveriges Radio's Ekot.
I see the incident as very serious, and above all because it is part of a larger pattern of problems with confidential documents that we have seen that this government has had, says Svenneling to Ekot.
After Prime Minister Ulf Kristersson (The Moderate Party) traveled to Ankara to meet President Erdogan, the folder with partially confidential information was left on a toilet at Arlanda. The material was found by a cleaner at the airport.
The Government Offices confirm the incident.
