So, anyone looking for socialism: You'll find some remnants in Norway, otherwise the only country still doing it in Europe on a limited scale, is Belarus.
Literally every country in Europe is socialist. No socialist country is more socialist than the other. It is really a black and white thing. You either live in a socialist country or you don't.

There are different types of socialism for sure (feudalism would be consider reactionary socialism for example), but let me assure you, Europe is entirely socialist.
