That is one of the many balances we will have to strike in the months and years to come as we recover from covid-19. There are, immediately, three things we are doing on that. The first is that we have brought in more staff, especially retired staff, and we want to keep them. They have been absolutely brilliant and a huge help to the NHS during the crisis. The second is providing more support to staff. I mentioned the mental health support, but this involves all sorts of other, wider support to staff right across health and social care. The third thing is making sure that we rebuild the NHS, gaining from the improvements that have been made in the eye of this storm, because there have been improvements to ways of working. Huge strides forward have been taken on the use of technology, and we have found areas where that has made a very big positive impact. Although there are, of course, parts of this crisis response that we want to roll back, there are other parts we want to pick up and take forward.
