The Chair of the Health and Social Care Committee makes an incredibly important point. The approach we are taking is a targeted one of repeat testing, which has started already but needs to spread much further. The reason is that some people in hospital settings are at higher risk, and it is better to focus the resources for repeat testing on those at higher risk. For instance, somebody working in finance might be at lower risk than somebody in a frontline setting. The NHS has a strategy on this, and I will write to him with further details of how that is going to work.
