Be careful with being explained politics from other countries, even sourced. If you asked a big part of the french population what are LFI's politics they'd tell you all sort of horrors that the media baselessly accuses them of simply because they are dangerous to the capitalistic system we live in. The formerly mainstream french "left" hates them too and always has.

Unfortunately more and more media all around the world is owned by more or less hidden oligarch wannabes.

I don't know swedish politics either, but I wouldn't trust random strangers on the internet to tell me what they are.
