if a young person goes on holiday to, say Ibiza, and gets drunk and robbed of all his money:

Would we expect the British Consulate to help him (or her) to return?

One rule for all. The costs covered by just a loan.

The same legal system has an opinion on her antics abroad.

The irony is that she has rights under British law, but her baby probably has less.

The only get-out I see is that without a passport it is difficult (not impossible) to prove who she is.

We need to see how her parents pronounce, re the way she was radicalised and by who. They need to be more vocal, and active in ther community. And we need news media that can handle the story accurately. What are the odds on the latter?
