Nothing new. Kristersson (of the "Conservative" party (M)oderaterna) being Kristersson, the right wing being the right wing. They have been running Sweden more or less for twenty years now, doing the market liberal dismantling and selling out and privatising everything they can and running the country in the shitter except for the economic elite and the ruthless capitalists. The last four years have been a right wing coalition with the nationalists (SD) as a "support party", being able to force their political agenda while appearing as opposition in parallel when it doesn't work out. The Christian Democrats (KD) have been touring together with the nationalists already and their leader is a republican party fangirl. The (L)iberal party leader hugged the nationalist leader a few months ago, welcoming collaboration despite the nationalist party pretty much dismissing all liberal politics, but then again so have L as they are now the "Forbid Everything and yay surveillance" flavour of liberalism. The only one to mildly oppose the nationalists on the right are the (C)enter party that are profiling themselves as a right wing green alternative, which is ironic considering they are the old farmers party that fought against any sort of environmental regulations for farmers.
But the left wing is not great either. The (S)ocial democrats have been doing the centrist creep since the early nineties and have participated in the market liberalism when it was popular. They have become a populist shell of the solidarity and workers party they once were. The Left (V) are the old Communist party and still so on paper, but their politics today are pretty much in line with the old school (S), though they still have some old totalitarian nutters in their ranks.
The Greens (MP) are theoretically outside the spectrum but clearly left leaning, as it coincides with their values and pragmatics when it comes to environmental issues.
This coming election seems to be very close and it's going to be a chiller. If the right wing gets in power with the nationalists, shit is going to get so much worse.
