May I first place on record our appreciation of the hon. Gentleman's efforts? Few in the House have done more to achieve progress on this matter and I pay tribute to him. That screening, I am advised, is in place, but it is important that we have the closest scrutiny, particularly of the groups that he refers to. That is why it is important that we work in those countries to stop the flow of those people. We must also work hard here: it is not always easy to identify the age of a trafficked child, so we must have the mechanisms in place to proceed to identify exactly who the individuals are.
