I thank my right hon. Friend for the breadth of the statement today. Necessarily, there is still a lot of detail to be worked out, not least on qualifications. For me, in talking to headteachers today, it has been humbling—not surprising, but humbling—to see the depth of their commitment to supporting their family and the whole of our society through this crisis. May I ask my right hon. Friend for flexibility, where necessary, to add to the designations of vulnerable children, as schools know their families best, and to add to the designations of key workers, where appropriate? May I also ask for schools to work together, where appropriate, in pairs or in clusters, particularly in areas where there are small schools?
