Have three theories
1 means to an end sacrificial daughter to stay in UK.
2 sent I India for marriage
3 family outcast, not wearing hair scarf like rest of females in family, so called honour murders have happened in UK.
Horrific apparently shame on a family means more than life in some cultures!.
Not convinced family should be allowed to stay in UK to help with enquiries, may
give wrong vibe!.
If they were to be sucessful precedent would be set to have extended family stay
in cultures where daughters are thought of as a burden, would open the floodgates!.
