Earlier on Tuesday, Prime Minister Boris Johnson said early indications suggest Omicron is more transmissible than the Delta variant.
He made the comment as he updated ministers on the COVID situation at a cabinet meeting.

Giving an account of the meeting, the PM’s spokesman said: “The prime minister said it was too early to draw conclusions on the characteristics of Omicron but early indications were that it is more transmissible than Delta.”
Downing Street also warned that it is still unclear what impact the vaccines have on the new variant.
Meanwhile, British drugmaker GSK has announced that its antibody-based COVID-19 therapy with US partner Vir Biotechnology is effective against all mutations of the Omicron variant.
The unpublished data shows that the companies’ treatment, sotrovimab, is effective against all 37 identified mutations to date in the spike protein, GSK said in a statement.
Another pre-clinical data showed that the drug had worked against key mutations of the Omicron strain.
Last week, it was approved for UK use by the Medicines and Healthcare products Regulatory Agency (MHRA).
