I will bring my comments to a conclusion by looking ahead. We need to adhere to the same principles that I've mentioned about doing enough but not too much. In terms of the self-isolation time: bring it down as much as possible, but only when the evidence allows that to be done safely, and I hope that that can happen soon, of course. We have to remember that we are still living in a time of pandemic and that strengthening those elements, perhaps where the Government has been too slow to take action, is more important than ever—ensuring that we ventilate so that any future waves don't have a major impact, and that we have that ventilation guidance in schools and so on. We are clearly in a more promising position now, and the right decision has been made to lift certain restrictions, but we have to be vigilant still. We need to continue to prepare, we need to put preventative steps in place and respond quickly and appropriately to a changing situation. That is what will enable us to be as resilient as possible in facing future problems.
