Just very briefly on resilience and testing—I know we've talked about this before—in terms of the lighthouse labs, obviously building up our own capacity is absolutely critical. There's an interesting experiment in the north-east of England, where they've taken a lighthouse lab effectively into public ownership, I suppose you might call it, and also they're targeting it at local authorities and universities, and local private sector working together. Interesting model; could that be applied in Newport and then connected with our own indigenous system? Ventilators was a key theme in the early phase of the coronavirus; ventilation is becoming mission critical as well. Are we going to be providing help for workplaces and public buildings to get better ventilation during this critical phase?
