From what I have seen and observed, I wouldn't be surprised if things aren't that different in Europe from the US, just somewhat worse on the whole. That is, antisemitism is found on all sides of the political spectrum including in the center. Also, that antisemitism is most common, and often most overt, on the right / far right. Share any studies you have supporting or refuting that though.

This covers many countries, and does have multiple years in many of them, but it doesn't distinguish by political views. Just gender, age, and religious affiliation by country.
