NHS leaders warn time is running out to establish track and trace strategy

PM said a 25,000-strong army of trackers had been recruited to identify the contacts of infected victims. Government's scientific advisers insist the system must be in place before any more restrictions are lifted. Rules limiting social contact could also be relaxed at that point, with a decision due at the end of next week. Ministers have admitted a tracking app being tested on the Isle of Wight will not be ready at the start. Security minister James Brokenshire said tracing system for 10,000 people can be launched before the app. Fears are mounting that the lockdown is eroding after thousands of sunseekers flocked to beaches and parks
