I don't know about other nations. In Germany we have had the Conservative Party ruling for 16 years as a right leaning Party, 4 years of a left party that implemented right wing neo fashist ideas, followed by another 16 years of conservative rule with more centeristic than right wing rule (the political void in the right was filled by the AFD, which has become a true fashist party in the last 10 years). The only "left" government we ever had in the last 36 years has been in the last 2, and they are heavily restricted by beeing in a coalition with a neo liberal right wing party.

So, at least for Germany, this just doesn't hold true.
