Socialism has evolved over the last 40 years, so it is hard to say one way or another. There are in reality only two countries that could fit the "socialist" mantra these days and that is Cuba and North Korea. And even Cuba is moving away from the socialist mantra by privatizing land and other capitalist ways.. China is not socialist anymore btw... and never really was.
There are few truly socialist parties in Europe these days. Those that are, are former communist parties under new names, with usually "Green" in the title. The traditional left wing parties have gone more and more towards the center and further away from the left.
But saying that, a transformation of the right has also happened in some countries, especially in Northern Europe. In Denmark for example, the traditional Conservative Party will have a hard time getting into Parliament at the next election, and this is a party that had the Prime Minister post 30 years ago (and it was a good Prime Minister at that..). In its place has come a more liberal right wing party, and of course the far right neo con racist borderline neo nazi parties.
Point is, the traditional views of political parties across Europe has changed a lot over the last 40 years in many countries.. in others they remain the same.. Spain comes to mind. Even in the UK, Labour has warped from its roots, and even the Tories has warped, although it seems that they want to go back to be the party of Thatcher. Times change, and those parties that do not evolve die out.
