I very much welcome the £500 that we've given to care workers, because they are very much in the front line of risk, looking after the most vulnerable people living in very close circumstances. I also very much welcome the mobile testing units that have been launched to enable residents and staff in care homes to get tested, to see whether they've got the virus. But I'm sure you'll acknowledge that one mobile testing unit for the whole of Cardiff and the Vale is insufficient to cover all the care homes and all those vulnerable senior citizens who we need to protect. So I wanted to probe your plans for enabling us to massively increase the numbers of testing units. One report talks about 94 teams working seven days a week. It would appear that we can't rely on health personnel unless we want to see all the other important health interventions they deliver abandoned, and I wouldn't want to see that. So I wondered what consideration has been given to recruiting other people. In your statement, you paid tribute to the voluntary sector, and I'm aware that, in Sheffield, the pilot for testing and tracing was led by a retired director of public health; it also involves volunteers in supporting the tracing aspect of it.
