She’s our citizen, she’s our responsibility. Why on Earth should some other country have to punish her or let her live in their country? Quite ironic when the ‘send them home,’ brigade don’t like it when the shoe is on the other foot. British imperialism at its finest.
That’s of course ignoring the fact she was only 15, brainwashed and groomed. Let her come back, if she’s found guilty of being linked to a proscribed terrorist group or some other charge then punish her under our laws, like any civilised country should.
