Illegal Migration Bill

In trying to answer my question, the Minister just reiterated what it says in the equality impact assessment. It was an important question. If the central tenet of the Bill is that children—accompanied or unaccompanied—not being given any dispensation will act as a deterrent, where is the evidence for that? In answering, the Minister said that this was the view of the department. Well it is the view of some children that the tooth fairy exists but, looking at the empirical evidence, it is quite clear that this may not be so. My question is clear: on what empirical evidence is the view of the department built, and when will this House get to see that evidence?
