Boris Johnson has repeated a widely mocked claim that no country has a working contact-tracing app after the Government was forced to shelve production of its own after spending almost £12 million.
Keir Starmer pressed the PM over his track and trace scheme and pushed on why ministers had shelved plans for their own app, after previously describing it as essential.
The Labour leader said: “Other countries are ahead of us. When are we going to have a working app?” Mr Johnson then repeated a claim made yesterday that Britain wasn't behind the curve and asked Mr Starmer to name one country with a successful app.
