Dido Harding, who heads the NHS test-and-trace service, is self-isolating after receiving an alert from her service.
The Tory peer posted an image of the “you need to self-isolate” app notification, and wrote: “Nothing like personal experience of your own products … got this overnight. Feeling well. Many hours of Zoom ahead.”
Lady Harding’s husband, the Tory MP John Penrose, has previously been told to self-isolate by the test-and-trace app after potentially coming into contact with someone who has coronavirus.
