Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what assessment he has made of the validity of reports that the NHS track and trace app will not work in (a) Croydon, (b) London and (c) other densely populated areas.

Following rigorous field testing and a trial on the Isle of Wight, we have chosen to bring forward a solution that brings together the work that NHSX and Google/Apple have carried out separately. This is an important step that will bring together the necessary functionality required to carry out contact tracing across all parts of the United Kingdom.
