I always enjoy listening to my right hon. Friend, but I am always slightly conscious when he moves from answering questions to displacement activity. Can we go back to the issue of base case and worst case? Quite specifically, when were the words “base case” changed to “worst case”—the precise date, please, and who authorised the change? When was it done? That is the first question, because I think the House needs to be able to understand why that decision was made.
The second issue concerns the Schengen database. I am fascinated to hear about these measures of mitigation; I am familiar with the database in my role as Chair of the Intelligence and Security Committee. This is undoubtedly a key piece of data for the security of the United Kingdom. What exactly are the mitigations that my right hon. Friend is talking about that will be an adequate substitute for the loss of access to this database on a no-deal Brexit?
