Lord Bracknell said:A real life poser ...
A former work colleague of mine was born in Hungary of Hungarian parents, who fled that country when the Russians invaded in 1956.
The family went to South Africa, where she grew up. She then married an Englishman, who brought her to Britain.
She subsequently divorced him.
Because she had fled Hungary in 1956, she was stripped of her Hungarian nationality. She was never offered South African nationality (and never wanted it). The South Africans accepted her as a Hungarian (because they didn't like the Russians). When she married the Englishman, she became entitled to a UK passport, but she lost that entitlement when she got divorced.
What nationality is she now? Not British, it would seem, But where should the UK authorities deport her to, since she has no entitlement to stay here?
Does it make any difference that, since her divorce, she has met an Englishman and they have had a child, but they haven't married? What nationality is she now? And what is the nationality of her child?
So you can "earn" a British passport but something can happen and you dis-earn it? Bizarre.
