Coronavirus: Prime Minister's Questions - 24 June 2020 - BBC News
Boris Johnson faces questions about virus test and trace programme
The prime minister and Labour leader clashed over coronavirus contact tracing apps – and the fact that England does not have one yet.

Boris Johnson said: “I wonder whether [he] can name a single country in the world that has a functional contact tracing app, because there isn’t one.”

Germany’s public health body, the Robert Koch Institute, has tweeted to say the app has been downloaded 12.6m times since then.

But we haven't yet seen figures from the German government on how well it is performing and how many people have received an alert as a result.

Two million people downloaded it (although 460,000 have uninstalled it since) – according to figures from the French government.

But just 68 people used it to say they had Covid-19 and only 14 people have been traced and warned they are at risk of infection.

A number of other countries around the world have also launched apps.
