I rise to speak briefly to amendments 48, 49 and 52 in my name. They have cross-party support, including from other Select Committee Chairs, because they are about safeguarding the role of Parliament and preventing the concentration of power in the hands of the Executive. Before I talk in detail about those amendments, I want to support new clause 53 and the words of my Home Affairs Committee colleague, the hon. Member for East Worthing and Shoreham (Tim Loughton). He is right that we need to continue with our historical obligations towards refugees and with the principle of family reunion, ensuring that child refugees are not separated from their family and do not lose their rights to be reunited with family members who can care for them, especially when families have been separated by persecution and conflict. He is also right that this is about preventing the people traffickers, the exploitation and the modern slavery that can cause such harm and blight so many lives. Our Committee has often found evidence that leads us to want the Dublin III process to work faster and more effectively, not for the principles behind it to be ripped up and thrown away. I therefore welcome the fact that, as the hon. Gentleman has said, Ministers have shown an interest in supporting the continuation of these historical obligations. I hope that that will be addressed if not in this Bill, then in either an immigration Bill or in the withdrawal agreement Bill in due course. The amendments I have tabled to clause 7 address the concern, raised by so many of us, that Parliament is being asked to hand over considerable powers to the Executive without sufficient safeguards. That concentration of powers in the hands of the Executive-a concentration not seen since the days of the infamous Tudor monarch-goes against the very reason why all of us were elected to this place: the legislature has an historic obligation to place checks on the power of the Executive, in order to prevent concentrations and abuses of power, in relation to Brexit or to anything else. It is an obligation that each of us takes on when we swear the oath at the Dispatch Box.
