Former Swedish security adviser on trial for allegedly mislaying classified papers

Henrik Landerholm, a longstanding friend of the Swedish prime minister, Ulf Kristersson, appeared on Monday in front of a packed gallery at Attunda district court in Sollentuna, north of Stockholm.

His trial is expected to centre on the events of March 2023 when Landerholm is alleged to have left documents in an unlocked safe at a hotel conference venue. Much of the proceedings will be held behind closed doors due to the information said to be contained in the documents.

One of the witnesses, a member of the military, will reportedly be questioned under a codename during the three-day trial. Witnesses are also expected to include staff at Gällöfsta Kursgård, a conference centre north of Stockholm where the documents were left.
