I have written at some length about the different classes of British citizenship, and how even if you are born a UK citizen, if you come from the wrong ethnic or national background you will always be a citizen on sufferance. Nowhere is that more clear than in the announcement by Home Secretary Sajid Javid that Shamima Begum, the British girl who left the UK at age 15 to join ISIS, was having her citizenship revoked, despite the fact that she a) was a child victim of international sexual predators and b) was born in the UK and has no other citizenship. Since the UK is barred by international treaties from rendering a person stateless, Javid had to argue that she wasn’t really stateless, since she could claim Bangladeshi citizenship through her mother. Even if she was born here and it was the failure of British authorities that allowed her to be groomed and trafficked, she has proved herself unworthy of the first-class citizenship that she was born with, and those colonials will just have to give her one of those cheap non-British citizenships.
Putting aside the autocratic air of a government official deciding, on the basis of a vague supposition that their citizenship is “not conducive to the public good”. At the very least, as long as the revocations were confined to people who had been nationalised as adults, and who retained dual nationality, there was some limiting principle other than ethno-nationalism. Now, anyone who simply could be eligible for another citizenship can be thrown out of their own country, at the stroke of the Home Secretary’s pen. Among those potentially affected, in addition to those potential traitors whose parents came from abroad, is of course any British person born in Northern Ireland — eligible for Irish citizenship — and any Jew, since they are eligible for Israeli citizenship.
A Home Secretary who decided that the presence of Jews in the UK was no longer “conducive to the public good” could, by Javid’s precedent, simply sign the appropriate order to “send them back where they came from”. No new laws are required.
