Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, with reference to the NHS covid-19 tracing app and in addition to the code for the app that has already been published, if he will publish (a) the code for the backend processing of data, (b) the third party data services to be used and (c) the administrative roles involving that data.

Alongside the source code for the app, we have already published documentation which sets out the full application and system architecture. The data protection impact assessment lists the data processors and their roles.
