The UK is already arriving at the point where daily deaths are beginning to fall, however there is still some way to go until the rest of the criteria are met.
The reorientation of the NHS towards handling the COVID-19 outbreak means the health service is currently coping.
Mr Raab said there were still “issues with the virus spreading in some hospitals and in care homes”.
He added: “The very clear advice we received is that any change to our social distancing measures now would risk a significant increase in the spread of the virus.
“That would threaten a second peak of the virus and substantially increase the number of deaths.
“It would undo the progress we have made to date and as a result would require an even longer period of the more restrictive social distancing measures.”
