Boris Johnson has set a 10-day target to deliver a coronavirus test and trace system so the lockdown can be further eased across the country.
The Prime Minster said the government has recruited a 25,000-strong army of trackers to identify the contacts of infected victims and prevent further outbreaks of the killer bug.
The Government's scientific advisers told Downing Street that before any more restrictions are lifted a scheme must be up and running, Mail Online reports.
Mr Johnson told the Commons the tracing scheme was almost ready, despite problems with a government app that was meant to help the process.
