I am grateful for the opportunity to speak. I will do so perhaps rather more briefly and concisely than many others have done, because I know that lots of people want to contribute to this debate. Up to now, I have sought not to encumber the House and the Government with lots of amendments to an already extensive and comprehensive Bill. I have certainly sought not to bind the Government's hands in the very difficult process of exiting the EU in the months and years to come-particularly in the complex and important negotiations, which received a substantial boost last Friday. No hon. Member should be in any doubt that there is a serious and growing prospect of our agreeing to a mutually beneficial conclusion to the Brexit negotiations. Why would anybody in this House not want that to happen? There is, however, an aspect of the Bill that merits a new clause. I am speaking primarily to new clause 53, which is in my name and that of other right hon. and hon. Members from all parts of the House. The new clause is designed simply to perpetuate an existing arrangement in family reunion rules. We should take great pride in our involvement in that arrangement. Many of us are concerned that if it does not continue, vulnerable children who are fleeing conflict in the middle east, in particular-this House has heard much about them in the last few years, and is familiar with the situation-could be detained in places of danger. We are doing much to help such children, and we need to do more. I have seen at first hand the benefits of the Dublin arrangements. My right hon. Friend the Member for Loughborough (Nicky Morgan) and I went to Athens as the guests of UNICEF earlier in the year to visit the refugee projects. I am aware that many other hon. Members have been to Greece, Italy and Calais to see the results of getting it wrong further up the line. The situation in Italy, in particular, is rather more extreme than that in Greece. In Greece, we saw UNICEF and other aid agencies working with a Government under great pressure, and doing a pretty impressive job. Some 30,000 refugees arrived in Greece in 2016, but the number of arrivals has since fallen to a more manageable level. That-not least the almost 3,000 unaccompanied children among those 30,000 refugees-still represents a serious challenge, however.
