I will not reiterate the facts of the Supreme Court judgment on the Northern Irish aspect. The hon. Gentleman can read those much more authoritatively in the judgment. I have said to him before in this House and reiterate to him again that there is more than one guarantee in this matter. The British Government are determined to preserve the peace settlement and all that underpins it; the Irish Government are determined to underpin it; and so is the Commission. I will say something nice about the Commission in this regard. When I spoke to Michel Barnier, my opposite number, he reminded me that he was involved in the original peace process. All the parties to this matter therefore have a vested interest in delivering what the hon. Gentleman wants.
