The "white people" concept is increasingly gaining popularity in Europe and especially among the European far-right though. This is due to the massive influx of non-European migrants over the past decades, which makes the racial divisions much more visible.
Likewise - there's either concern about competition from eastern Europeans (who are as pale as Brits are), or the increase in Islamic terrorism (which is obviously a religious concern rather than a racial one).
Both are not advocating any kind of racial supremacy but rather self-interest, and - like them or not - relatively common as judged by recent election results.
