I was actually thinking about RN, the French leading far right party. Their main point relates to security, immigration and general nationalism. But when it comes to the economy, they tend to support welfare (except for immigrants of course...), support local farmers, and nationalize highways (which are private in France).

But yes, they promise what people who may vote for them want, and it turns out, on the economic side, it is slightly leaning left. The general sentiment may be different in Germany.
