It is always a pleasure to follow the hon. Member for Rhondda (Chris Bryant), who made some very serious constitutional points with great colour and eloquence. I am grateful to hon. and right hon. Members who have contributed to this debate through their various amendments and speeches. My approach over the course of my speech-I suspect that it will take me an hour to get through it-will be to take clause 9 first, and then to come on to clauses 16 and 17 as well as schedule 7. It may be helpful to hon. Members who want to intervene to know that I will first explain the function of clause 9 and why it is necessary, and then set out some of the illustrations that the hon. Member for Greenwich and Woolwich (Matthew Pennycook) suggested were required. I will come on to talk about the limits, and then I will address the amendments, including amendment 7, which was tabled by my right hon. and learned Friend the Member for Beaconsfield (Mr Grieve). The key issue will come down to timing, so I will also touch on that, but first, let me set the scene. Clause 9 highlights the interaction between diplomacy at the international level and the domestic legislative preparation for Brexit. The Government are committed to securing the best deal that we can with our EU partners for the whole United Kingdom against the very acute time pressure set out under the article 50 process imposed on us. Clause 9 enables regulations to be made for the purposes of implementing the withdrawal agreement. It is now, as hon. Members have said, a supplementary provision to give us agility in the negotiations and the flexibility of legislative procedure to deliver the best deal under time pressure. The Secretary of State for Exiting the European Union announced to this House on 13 November the Government's intention to bring forward new primary legislation in the form of the withdrawal agreement and implementation Bill to give effect to the major elements of the withdrawal agreement. That will include citizens' rights, the implementation period, the financial settlement and the other issues wrapped up within the exit negotiations.
