Warnings that contact tracing not ready as lockdown relaxed in England

England has seen the biggest relaxation of the lockdown since it was imposed 10 weeks ago with as many as 6 people allowed to meet outdoors. 

There has been criticism from some scientists that this is too much too soon — and risks a second big wave of coronavirus infections. 

A key part of easing the lockdown is the government's ability to identify and tackle outbreaks of coronavirus through a new system of contact tracing. The Prime Minister promised that system in England would be up and running and effective from June 1st. But there have been warnings that it isn't ready. 

Some children in England have gone back to school. Primary schools are being asked to reopen for children in Reception, Year 1 and Year 6. Some nurseries have opened too.
