Thank you, Mr Speaker. I would like to ask the Secretary of State for three pieces of data, all of which are essential for this strategy. First, what level of new daily infections do we need to be down to before contact tracing happens for all new infections? Secondly, how many daily tests will the test and trace system need? Thirdly, if we are going to introduce weekly testing for all NHS and care-home frontline staff, when will our testing capacity be sufficient to deliver that on top of test and trace?
