Firestorm
Pedant
NO NO NO!!
She can rot there for all i care, she made her decision, still to this day has no regrets about joining isis and is unrepentant about her actions.
If we let her back in to the country, she will be seen by extremists as some kind of living martyr, and in my opinion i view her as a more dangerous individual now than we she left at 15 years old.
It appears that she is a british citizen , who as yet has no criminal record (although that will change) . I don't think there is any way she can be stopped from returning.
However, going out and bringing her home is a different matter and I can't see that happening.
If she can make her way back , let her, and then arrest her once she is here
