Germany is less than four weeks away from rolling out a contact-tracing app to support the easing of lockdown restrictions, the country’s health minister has confirmed.

The announcement comes after Chancellor Angela Merkel revealed earlier this week that pupils will return to school from 4 May and that some shops will be allowed to reopen next week.
