This is certainly a problem that we have fixed. The computer glitch and error to which the right hon. and learned Gentleman refers has been addressed. All the 16,000 people he refers to have, in fact, got their positive test results and should be self-isolating. As soon as we became aware of the missing data, we brought in 800 people to chase up those index cases, and we continue to chase their contacts. I think it will be for the reassurance of the House and the country that the missing data points do not, now that we look at them, change in any way our assessment of the epidemiology—the spread of the disease. That is why we continue with our package to suppress the virus not just nationally, but locally and regionally.
