"She is in pain and having trouble walking. A sad start to Folk och försvar," says communications chief Odd Guteland to TV4 News.
Andersson has twisted her knee and has had to visit the local healthcare center. On , she writes about the accident herself:
"I really love skiing. It has become a bit too much of that this week. My knee therefore needs to rest for a while now," she writes next to a picture of herself with crutches.
On Sunday, the S-leader is scheduled to give a speech at the Folk och försvar conference in Sälen. However, there is no danger for her participation there.
