I thank my right hon. Friend for his important question. First, all announcements were made both in the conventional way and to the House, as Mr Speaker would expect. Secondly, as my right hon. Friend will understand, measures are always under review. Decisions will be taken through the consultative process within Government based on evidence, based on discussions and based on a number of facts. The virus, of course, is changing, although it is still with us. The vaccine roll-out is a new element, a new consideration, in terms of the nature of the measures that are being taken. It is fair to say that there has been a layered approach with these measures. As we have seen, there has been escalation and de-escalation. Right now, we have escalated the measures through the banning of the travel corridors, so these measures will be under review. Naturally, as the roll-out progresses, new strains may or may not materialise internationally. We will obviously have to take everything into consideration when it comes to permanency or the timetabling of the application of certain measures.
