Orban is somewhat of a different story, though you might be right. I didn't really intend to include Eastern European countries though.
I remember unproven, but persistent rumours about the Kremlin may be aiding League of Polish Families (hard anti-EU right) and Samoobrona (not really left or right, more an eclectic populist movement). Both were noticeably pro-Russian.
It may sounds silly that Putin would prefer PiS, given their anti-Russian behavior, but I wouldn't be surprised if the Kremlin preferred to have a hostlie Polish government than friendly one (regimes likes to have external enemies).
