First of all, there doesn't seem to be much difference between the"left" wing and the "right" wing parties in Europe these days anyway. Second, most of the so called "far-right" parties tend to be fairly left wing on the economic issues.
The thing that receives little notice nowadays is that the fascists (which many far-right European parties are modeled on) tended to have fairly leftist economic views.
Exactly. The BNP have this crazy idea of abolishing the income tax (which is one of the few economic issues thaey would be considered "right wing" on) while spending through the roof on healthcare, pensions, defence, etc.
