Currently a collapse is not on the cards, but I am very surprised if the government lasts until the end of it's term.
Either the Swedish People's Party gets fed up and leaves or the True Finn party (un)intentionally forces it to collapse, so that they can shift the blame coming from rough political actions on other government parties. They are horrible in doing anything constructive and when they mess up, they blame others. Same goes with the National Coalition, but at least they have some sense or responsibility (that does not prevent them from making decisions that hurt many and benefit few).
