"According to its constitution, the BNP is "committed to stemming and reversing the tide of non-white immigration and to restoring, by legal changes, negotiation and consent the overwhelmingly white makeup of the British population that existed in Britain prior to 1948".[18] The BNP proposes "firm but voluntary incentives for immigrants and their descendants to return home".[19] The party also advocates the repeal of all anti-discrimination legislation, and restricts party membership to "indigenous British ethnic groups deriving from the class of ‘Indigenous Caucasian’". The BNP also accepts white immigrants that are assimilated into one of those ethnicities.[18] The BNP asserts that there are biological racial differences that determine the behaviour and character of individuals of different races, although it claims that it does not regard whites as superior to other ethnic groups,[20] and that preference for one's own ethnicity is a part of human nature.[19] Historically the BNP (including Nick Griffin) was overtly anti-Semitic; in recent history the BNP has instead focused on Islam.[21]"
