I do just want to clarify the decision to move to level 3 and say that schools and early learning services will be open for those who need them was done on the basis that there was no evidence of widespread community transmission and a very, very low chance of COVID coming through the gate or through the door in the first place. When we make that decision to move down to level 2, where we'll see schools and early learning services much more open for a much greater number, again, a big part of that—regardless of the debate around whether young people can carry it and transmit it, a big part of the Government's thinking around that is that the risk of there being undetected COVID cases that could come through the gate of school or early learning in the first place is very, very low. Therefore, the risk of it spreading in a school setting is very, very low. But one of the critical things, of course, in that is making sure we've got very rapid response so that if anything did happen, we can close that school down very quickly and we can do the contact tracing required.
