Puts me in mind of Alex Batty, the kid who went missing for years and was recently found in France.
The news (Radio 6 I think I heard it on - possibly Radio 5) was saying that they were waiting for his passport to be sorted so he can go home.
Why? Just let the kid go home! I suppose you could argue that after all these years what difference does a few days make, but seriously, what's the point? When he gets home he'll want to leave the country almost immediately?
Personally I find the whole thing about passports, nationality, borders and the movement of humans far too complex. Just let people be where they want to be.
What's that Suella? Billions of them want to be in the UK? Rishi was right - everyone should learn maths to a competent level.
