Whitehall whistleblower says mistake was flagged to Matt Hancock before he resigned in June but never publicly admitted
Many thousands of people may have isolated unnecessarily because a government error meant they were “pinged” by the Covid app for a “close contact” in the prior five days rather than two days, a Whitehall whistleblower has told the Guardian.
As the isolation rules for double vaccinated people were relaxed on Monday, it has emerged that users were never told the app could notify of contact with an infected person as far back as five days before the positive test.
