That would depend on the referrals made from the prison service. It's difficult, because when they're within the prison service, they're in a non-devolved service and then, if they're going to leave, they'll very quickly come into contact with, in the great majority of cases, devolved services, whether it's housing support or whether indeed it's social care needs that a number of people have. If you think about the prison in Usk, a lot of people there are actually quite old and they have a range of care and support needs. But the testing should be in accordance with our broader testing policy, whether people are unsymptomatic, and, of course, that goes for staff as well.
