As many as 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 per cent increase from Saturday’s total of 1,898 UK cases.

The new Level 4 grading means the epidemic is 'in general circulation, transmission is high and direct Covid-19 pressure on healthcare services is widespread and substantial or rising', according to the UK Government.
