At the start, when the number of cases was very small, we had enough tests to test everyone who had suspected symptoms. The number of cases has risen exponentially and the number of tests has been increased, but we need to make sure that the tests we have available are there for saving lives. We hope that the introduction of a home test or equipment for bedside testing, which my right hon. Friend and I have discussed previously, will enable us to increase the number of tests radically, and get ahead of the epidemiological curve as soon as possible. We are in live negotiations about bringing that in.
