Does this create a two-tier system? Effectively, yes. If both your parents were born in the UK and you do not have dual nationality, it would not be possible for the Home Office to strip you of your British citizenship, as this would leave you stateless. But for a British child of a dual national or immigrant, who is eligible for another nationality, it would be. Lord Anderson, a former independent reviewer of terrorism legislation, said it "effectively brings about two classes of citizenship".
