His ministry lost a no-confidence vote in parliament, but no-one else was able to form a new government so he was asked to form a new one.

This latest announcement is that he will be stepping down as the leader of the Social Democrats. There's a new election in Sep 2022, and to me (a Swede) it looks as if no-one is interested in an extra snap election right now (the regular election will be held in Sep 2022 as planned anyway).
