@cy Yes— but

1) it's HMG's opinion that matters here, and future governments can abuse the power

2) it's not a good thing that if they want to deport someone, it's easier if they're Jewish.

So, you may know that the British government is going to make a law that if you're eligible for citizenship elsewhere your British citizenship can be revoked— even if you don't actually have citizenship there, and even if the other state doesn't agree that you're eligible.

Well, according to a Government answer in the Commons, it turns out that that applies to Israel's law of return. Thus *any* Jewish person can have their British citizenship stripped unilaterally.
