Jake you must learn the difference between Conservative/Rightist parties and neo-fascist parties. The Front National in France is a Nazi sympathizing, neo-fascist movement. Their politics are more towards the populist end than the conservative end of the political spectrum. The same is true of the Lega Nord in Italy which is more of a populist, neo-fascist party than a Conservative Party. The more obvious choices are the Alleanza Nacionale, Biancofiore, or (rather oddly) the New Italian Socialist Party in Italy. You have to see that not every party they label as being on the "right" is actually conservative or right-winged instead of authoritarian.
That is a common misconception. the Front nationale, like the SVD in switzerland, is a paleo-conservative party that panders to the xenophobia of the voters to get votes and visibility. However, neither the FN, nor the Swiss SVD, nor some(but not all) european "extreme right" parties are fascist or Nazi, because they do not support left-wing economic policies, unlike, for instance, the British BNP, who do supprots left-wing economic policies, and who is in fact a fascist party. I suggest you read the Front National platform on theri website, it might clear some misconception I too had before reading it.
