I welcome the hon. Lady to her place. Stakeholder engagement in this matter has been crucial, and continues to be. We have been consulting not only the ethics advisory board for the app, which is chaired by Professor Sir Jonathan Montgomery, but the Information Commissioner, the Centre for Data Ethics and Innovation, the National Data Guardian and many others. Trust is important—it always is—but this app is from NHSX, the tech arm of the NHS, and in this country we trust our NHS with our data. The app is going to be heavily protected and I am confident that it will be very popular.
