May I commend my right hon. Friend on the swift action that he takes, and the way in which he comes before this House on a regular basis to update us? I think that is important, as are the lessons that are being learned from other countries. In his statement, he actually announced something as well as the lockdown in Bolton, which is that his current guidance regarding people in high incidence areas socialising only with those in their own households will be turned into law. That is presumably to strengthen enforcement. Could he take a moment to explain what that will mean in practice and whether there be an impact on venues that may be required to be part of that enforcement process, and when does he intend to bring that before the House for discussion?
