The BNP proposes to reintroduce corporal punishment, and to make capital punishment available for paedophiles, terrorists and murderers. In addition to increasing military defence spending, the BNP plans to reintroduce compulsory national service. The BNP proposes that men should keep a rifle and ammunition in their homes. It proposes "to end the conflict in Ireland by welcoming Eire [sic] as well as Ulster as equal partners in a federation of the nations of the British Isles".
The BNP requires that all members must be members of the "Indigenous Caucasian" racial group. The party does not regard non-white people as being British, even if they have been born in the UK and are naturalised British citizens. Instead, Griffin has stated that "non-Europeans who stay", while protected by British law, "will be regarded as permanent guests".The party has stated that it does not consider the Jewish, Hindu or Sikh religions to have a significantly detrimental or threatening effect, having several members with Jewish ancestry, but does not accept practising Sikhs or Hindus as culturally or ethnically British. In pursuit of the policy, the BNP has previously worked with extremists from the Sikh and Hindu communities in an anti-Islamic campaign and actively tried to win Jewish votes.The BNP is opposed to mixed-race relationships on the stated ground that racial differences must be preserved; the party said that "when whites take partners from other ethnic groups, a white family line that stretches back into deep pre-history is destroyed." Nick Griffin stated: "...while the BNP is not racist, it must not become multi-racist either. Our fundamental determination to secure a future for white children is restated, and an area of uncertainty is addressed and a position which is both principled and politically realistic is firmly established. We don't hate anyone, especially the mixed race children who are the most tragic victims of enforced multi-racism, but that does not mean that we accept miscegenation as moral or normal. We do not and we never will"
