At least one of the documents concerned a secret conversation between Landerholm and the US national security adviser Jake Sullivan. The focus during the meeting was Sweden's strategy for getting the Nato application approved by Turkey. The documents were based, among other things, on security-classified information from the Security Police and the Defence Forces.
The meeting was held at lunchtime on March 13, 2023, but it is unclear where it was held and whether it took place physically or via video. Afterward, Landerholm took a taxi to Gällöfsta course center, where the documents were later found.
The conversation with Sullivan took place in the middle of the ongoing Nato process. The day after, Sullivan had an official meeting with the Turkish president's chief adviser.
Landerholm is charged with negligence with secret information and the trial begins next week. He denies the crime.
