jenny. i know that public health england are also looking into it. lastly, can i turn to harrisonthe looking into it. lastly, can i turn to harrisonjones at the metro, please? thanks very much. the health secretary promised 100,000 test would be carried out daily by the end of the month before the goalpost was seemingly moved to talk about capacity protesting. less than 29,000 tests today, when will we reach the prime minister's previous target of 250,000, and how and when we'll be testing be opened up beyond key workers and their families? and ifi key workers and their families? and if i may, just an extra question on contact tracing, the new nhs app — are we contact tracing, the new nhs app — are we expecting to follow a similar model to south korea, tracking people by gps signals? on the 100,000, this is the number of tests versus the capacity, and it is a well worn discussion. i think what well worn discussion. i think what we have been finding is that capacity has been rising pretty fast, as i mentioned, professor newton said yesterday that he thinks we will get it 100,000 am
