First Minister, what would be devastating economically would be the need for either a second lockdown or a localised lockdown, and one of the key measures that you've put in place is test and tracing. Your figures for returning the results from test and tracing are getting worse. The figures for 24-hour delivery are under a 50 per cent response rate, and for 48 hours only 66 per cent of tests are returned to the people who've put themselves up for a test. How are you going to improve these figures to get closer to the 90 per cent that most experts believe provides an effective testing structure that would protect us economically, and also our health?
