Keep her out.
When she left the UK to support Isis she saw peoples decapitated heads and it didnt bother her.
What did she have to do to prove she was loyal to Isis? maybe kill a prisoner?
Her father is in Pakistan area so why doesnt she go there to live with him?
I think her Lawyers have told her to dress like a young British girl & she will get a lot of sympathy.
Then when she gets back here she can start wearing the Hijab again and maybe write a book about her experience.
