The country’s four chief medical officers and NHS England’s national medical director have recommended to ministers that the UK go up to Level 4 from Level 3.

The decision to increase the alert level follows advice from the UK Health Security Agency (UKHSA) after a further 1,239 confirmed cases of the Omicron mutation were recorded in the UK as of Sunday.

It brings the total number of UK cases of Omicron to 3,137, a 65% increase from Saturday’s total of 1,898 UK cases.
