We are not only fixing the problems; as the hon. Gentleman will know, we are building four more Lighthouse labs. On the machines in question that needed to be supplied, we have secured them, and we are moving forward. I am confident that we will have the capacity to do 500,000 tests per day by the end of October. That is an extraordinary thing. On the ambition for mass testing, I think that is a great thing, and the Government will support it.
