Prime Minister Boris Johnson is set to launch an alert system to rank the threat level of coronavirus in England.

BBC reports that this new development will be revealed in his lockdown speech later.

The system is to be as part of the PM’s televised address at 19:00 BST and which will use a scale of one to five and be adjusted according to data.

On changes and new measures, Mr Johnson will also explain any changes to the lockdown measures.

Concerning regular reminder about the danger the virus poses, the PM introduced a new slogan, telling the public to “stay alert, control the virus, save lives”.

However, the places where the “stay at home” advice will remain in place are: Scotland, Wales and Northern Ireland.

In his statement, the prime minister tweeted a graphic setting out the new guidance with the message: “Everyone has a role to play in helping to control the virus by staying alert and following the rules.

“This is how we can continue to save lives as we start to recover from coronavirus.”
