UK Borders Bill

I thank my hon. Friend for that very comprehensive and informative reply, which I am sure the whole House will have enjoyed listening to as much as I did, but can he help me a little more on the question of being 17 and a half? It seems to have sinister overtones, which I do not fully understand. I wonder whether my hon. Friend fully understands the significance of being 18. Once young people are 18, for example, do they have more rights than they did at 17 and a half? On the question of disappearance, is my hon. Friend aware of the ECPAT report—End Child Prostitution, Child Pornography and Trafficking of Children for Sexual Purposes—which showed that 48 children in the care of three local authorities disappeared last year? Will the Bill help?
