I am not sure you were in the Chair, Madam Deputy Speaker, when I addressed that precise question in my statement. Not having the contact details happens in about 0.1% of tests. In this case, we think the test was done as part of a home test kit, when it is incumbent on the individual to set out those details. Home test kits can be sent to someone’s home, in which case of course we have the details of where it was sent. Alternatively, in response to surges, tests can be taken round by local authority teams and dropped off. We therefore need to find out exactly where this test was dropped off. What the hon. Lady omitted to say is that the team has done a good job of narrowing down where that may be to 379 households. The call-out at the weekend was answered with a number of leads, and we are working hard to make sure we find the individual concerned.
